Аннотация:
We demonstrate that ferromagnetic metal/insulator/semiconductor hybrid structures represent a class of materials with the giant
magnetoimpedance
effect. In a metal-insulator-semiconductor diode with the Schottky barrier fabricated on the basis of the Fe/SiO2/n-Si structure, a drastic change in the impedance in an applied magnetic field was found. The maximum value of this effect was observed at temperatures of 10–30 K in the frequency range of 10 Hz–1 MHz where the ac magnetoresistance and magnetoreactance ratios exceeded 300% and 600%, respectively. In the low-frequency region (<1 kHz), these ratios could be controlled in wide range by applying bias to the device. The main contribution to the impedance when measured at temperatures corresponding to the strongest magnetic-field sensitivity comes from the interface states localized near the SiO2/n-Si interface and the processes of their recharging in an applied ac voltage. The applied magnetic field changes the energy structure of the interface states, thus affecting the processes of the charging dynamics.

Аннотация:
We report some ac and dc magnetotransport phenomena in silicon-based hybrid structures. The giant impedance change under an applied magnetic field has been experimentally found in the metal/insulator/semiconductor (MIS) diode with the Schottky barrier based on the Fe/SiO2/p-Si and Fe/SiO2/n-Si structures. The maximum effect is found to observe at temperatures of 10-30 K in the frequency range 10 Hz-1 MHz, Below 1 kHz the magnetoresistance can be controlled in a wide range by applying a bias to the device. A photoinduced dc magnetoresistance of over 104% has been found in the Fe/SiO2/p-Si back-to-back Schottky diode. The observed magnetic-field-dependent effects are caused by the interface states localized in the insula-tor/semiconductor interface. (C) 2014 Elsevier B.V. All rights reserved.

We report the giant
magnetoimpedance
effect in a ferromagnetic metal/insulator/semiconductor (MIS) diode with the Schottky barrier based on the Fe/SiO2/n-Si structure. It was established that the applied magnetic field strongly influences the impedance of the structure in the temperature range 10—30 K. In this range, there is the pronounced peak in the temperature dependence of the real part of the impedance at frequencies from 10 Hz to 1 MHz. The effect of the magnetic field manifests itself as a shift of the peak of the real part of the impedance. Under the action of a bias voltage of 5 V, the peak of the real part of the impedance similarly shifts toward lower temperatures with and without applied magnetic field. © (2015) Trans Tech Publications, Switzerland.

Аннотация:
Extremely large magnetotransport phenomena were found in the simple devices fabricated on base of the Me/SiO2/p-Si hybrid structures (where Me are Mn and Fe). These effects include gigantic
magnetoimpedance
(MI), dc magnetoresistance (MR) and the lateral magneto-photo-voltaic effect (LMPE). The MI and MR values exceed 10(6)% in magnetic field about 0.2 T for Mn/SiO2/p-Si Schottky diode. LMPE observed in Fe/SiO2/p-Si lateral device reaches the value of 10(4)% in a field of 1 T. We believe that in case with the Schottky diode MR and MI effects are originate from magnetic field influence on impact ionization process by two different ways. First, the trajectory of the electron is deflected by a magnetic field, which suppresses acquisition of kinetic energy and therefore impact ionization. Second, the magnetic field gives rise to shift of the acceptor energy levels in silicon to a higher energy. As a result, the activation energy for impact ionization significantly increases and consequently threshold voltage rises. Moreover, the second mechanism (acceptor level energy shifting in magnetic field) can be responsible for giant LMPE.

Аннотация:
The magnetoresistive effect in MnSe1−XTeX manganese chalcogenides with a substitute concentration of X = 0.1 is studied by impedance spectroscopy. The
magnetoimpedance
above the Neel temperature is found. The obtained experimental data are explained in the framework of the model of existence of magnetic nanoareas of two types. Two activation energies in the low- and high-frequency regions are determined from the frequency and temperature dependences of the permittivity described in the Debye model. The extrema found in the temperature dependence of the pyroelectric current are consistent with the maxima in the temperature dependence of magnetization. Temperature dependence of the carrier relaxation time is established. The magnetocapacitance of the MnSe1−XTeX solid solutions is found. The change in the carrier type above the Neel temperature and the temperature of the transition to the magnetically ordered state in the MnTe nanoarea is established.

Аннотация:
Present review touches upon a subject of magnetotransport phenomena in hybrid structures which consist of ferromagnetic or nonmagnetic metal layer, layer of silicon oxide and silicon substrate with n- or p-type conductivity. Main attention will be paid to a number gigantic magnetotransport effects discovered in the devices fabricated on the base of the M/SiO2/n(p)-Si (M is ferromagnetic or paramagnetic metal) hybrid structures. These effects include bias induced dc magnetoresistance, gigantic
magnetoimpedance
, dc magnetoresistance induced by an optical irradiation and lateral magneto-photo-voltaic effect. The magnetoresistance ratio in ac and dc modes for some of our devices can exceed 106% in a magnetic field below 1 T. For lateral magneto-photo-voltaic effect, the relative change of photo-voltage in magnetic field can reach 103% at low temperature. Two types of mechanisms are responsible for sensitivity of the transport properties of the silicon based hybrid structures to magnetic field. One is related to transformation of the energy structure of the (donor) acceptor states including states near SiO2/n(p)-Si interface in magnetic field. Other mechanism is caused by the Lorentz force action. The features in behaviour of magnetotransport effects in concrete device depend on composition of the used structure, device topology and experimental conditions (bias voltage, optical radiation and others). Obtained results can be base for design of some electronic devices driven by a magnetic field. They can also provide an enhancement of the functionality for existing sensors.

This paper presents the results of the study the transport properties of the SOI-based structure. Measurements were carried out on an alternating current with an external magnetic field in a wide temperature range. The influence of the magnetic field was found. We associate this effect with the influence on the surface states located at the interface, this appears as a change of the energy of their levels. This effect is enhanced by the nanoscale of the silicon channel.

Аннотация:
This article presents the results of a study of the transport properties of metal/insulator/semiconductor (MIS) hybrid structures in alternating current (ac) mode. We prepared a series of samples with different layers of metal, insulator, and semiconductor. We prepared a series of samples with different layers of metal, insulator and semiconductor. Ferromagnetic Fe and non-magnetic Cu and Mn were chosen as metals, the insulators were SiO2 and Al2O3, and n- and p-type Si substrates were used as semiconductors. Temperature dependence of the real part of the impedance showed peculiar peaks below 40К for different combinations of metals, insulators and semiconductors. For all samples the effect of the magnetic field on the transport properties was studied. At low temperatures, the magnetic field shifts peaks toward higher temperatures. Metal magnetic state does not significantly affect this phenomenon. Changing the type of the insulator and its thickness also did not cause any significant effect. However, the effect was observed for samples with different composition. Moreover, the type of conductivity of the substrate, as well as the type of metal, determines the value of
magnetoimpedance
. The main role in the
magnetoimpedance
effect is played by recharge of the energy states localized at the insulator/semiconductor interface. This mechanism allows obtaining a MI effect even in “nonmagnetic” MIS structures;
magnetoimpedance
can be either positive or negative, depending on temperature and frequency. We suggest that the observed ac magnetotransport phenomena could be used for creating magnetic field sensors, working on new principles.

Аннотация:
New multifunction materials in the AgXMn1‒XS (Х = 0.05) system have been synthesized and investigated in the temperature range of 77‒500 K in magnetic fields up to 12 kOe. Near the temperature of the magnetic transition (ТN = 176 K), the anomalous behavior of the temperature dependence of magnetization has been observed and has been attributed to the formation of ferrons. An analysis of the infrared spectroscopy data and I‒V characteristics has revealed the spin-polaron subband splitting. Several conductivity channels have been found from the impedance spectra. The temperature and magnetic field dependences of the carrier relaxation time have been obtained. The magnetoresistance (−21%),
magnetoimpedance
(−65%), magnetothermopower (−40%), and photoconductivity effects have been detected. The majority carrier type, density, and mobility have been determined from the Hall-effect measurement data. The observed effects have been explained using a ferron model.
Синтезированы и исследованы новые многофункциональные материалы системы AgXMn1-XS (Х=0.05) в интервале температур 77-500К в магнитных полях до 12 кЭ. В близи температуры магнитного перехода (ТN=176К) наблюдается аномальное поведение температурной зависимости намагниченности, вызванное образованием ферронов. Найдено расщепление спин-поляронной подзоны из ИК спектроскопии и вольт-амперных характеристик. Установлено несколько каналов проводимости из спектров импеданса, отличающихся частоте. Определена зависимость времени релаксации носителей заряда от температуры и магнитного поля. Обнаружено четыре эффекта: магнитосопротивление (-21%), магнитоимпеданс (-65%), магнитотермоЭДС (-40%) и фотопроводимость. Найдены: тип, концентрация и подвижность основных носителей заряда из холловских измерений. Обнаруженные эффекты объясняются в модели ферронов.

Аннотация:
The transport properties of the TmxMn1–xS (x ≤ 0.15) solid solutions in the temperature range of 200–600 K have been investigated. The temperatures of lattice polaron pinning accompanied by the lattice strain, condensation of the infrared modes, and thermionic emission have been determined. The change of the carrier sign with temperature has been found from the Hall coefficient data and dragging of electrons by phonons, from the thermopower data. The dependence of the magnetoresistance on the concentration, current, and voltage has been established from the I–V characteristics measured without field and in an applied magnetic field of H = 8 kOe in the temperature range of 300–500 K. The functional temperature dependence of the carrier relaxation time has been determined using the impedance data. The concentration region with the
magnetoimpedance
sign varying with frequency and temperature has been found. The increase in the relaxation time of the induced electric polarization with increasing concentration of thulium ions has been observed. The experimental data have been interpreted in the framework of the Debye and Maxwell–Wagner models, as well as the theoretical model for the Rashba spin–orbit interaction.
