Аннотация: Correlations between the direct and inverse magnetoelectric effects in orthorhombic DyMnO3 single crystals have been investigated. In the inverse magnetoelectric effect, the magnetic moment of the crystal appears to have a contribution that is sinusoidal oscillating in ac electric fields below the temperature TFE of ferroelectric phase transition. The first and the second harmonics of the inverse magnetoelectric effect are clearly detected. The magnetoelectric susceptibilities α and β, corresponding to first and second harmonics, are found to correlate with the derivative of polarization with respect to the magnetic field. The influence of the magnetic and electric regimes during cooling on magnetoelectric effects has also been studied. The maximum change in the magnetic moment of a sample under the action of electric fields is observed under the same (T, H) conditions as the rotation of the spontaneous polarization vector from the crystallographic c direction to the a axis in the magnetic field H || b.

Аннотация: The magnetostatic and magnetic resonance properties of the Y0.5Sr0.5Cr0.5Mn0.5O3 polycrystalline system have been experimentally investigated. The predominance of the intracrystalline ferromagnetic interaction and the antiferromagnetic character of the intercrystallite interaction have been established. The magnetic resonance spectrum in the magnetically ordered region consists of two lines. The high-field line corresponds to the interacting parts of polycrystal shells and the low-field peak is related to the disordered system of ferromagnetic particles.

Ключевые слова (''Своб.индексиров.''): hole-doped manganites--thin films--magnetic measurements--spin-glass behavior--x-ray magnetic circular dichroism
Аннотация: Magnetic properties of the Pr0.8Sr0.2MnO3 and Pr0.6Sr0.4MnO3 polycrystalline films have been studied using temperature and magnetic field dependences of the static magnetization and X-ray magnetic circular dichroism (XMCD) spectroscopy. For the both compositions, the difference between the temperature dependences of magnetization obtained in the zero fields cooling (ZFC) and field cooling (FC) modes has been revealed. The ZFC curves demonstrate a pronounced maximum at temperature Tm. It is shown that the Tm value dependence on the magnetic field follows the Almeida-Thouless line typical for the classic spin glass, what allows us to assume the possible spin-glass behavior of the films. Effect of the disorder in a direction of the crystallites easy-axis on the difference between FC and ZFC curves has been discussed also. Magnetic field dependences of the sample magnetization are presented by the hysteresis loops with the shape changing upon temperature variation. This behavior has been attributed to the effect of crystallographic anisotropy and Pr ions. The spectra and magnetic field dependences of XMCD at the Pr L2- and Mn K-edges have been studied at 90 K. The magnetic field dependences of the XMCD at the Pr L2-edge had shown Van Vleck paramagnetism from Pr3+ ions. © 2016 Elsevier B.V.

Ключевые слова (''Своб.индексиров.''): thin films--manganites--crystal structure--electrical transport--electronic properties--magnetic circular dichroism
Аннотация: The features of electronic structure of La0.7Sr0.3MnO3 Pr0.8Sr0.2MnO3, and Pr0.6Sr0.4MnO3 polycrystalline films of different thickness have been investigated using magnetic circular dichroism (MCD) in the range of 1.1–4.2 eV. The temperature behavior of the samples electrical resistance were also has been studied. It was found that films with high Sr content (0.3 and 0.4) act as high-temperature semiconductors, while the maximum in the temperature dependences of resistivity these films indicates the transition of the samples to the metallic state at some temperature TM-S, which is different for different sample thickness. The films with the lower Sr content (0.2) act as insulators in the used temperature range. The MCD spectra have been decomposed to the Gaussian-shaped lines, and the temperature dependence of intensity of each line has been analyzed in comparison with temperature dependence of the films magnetization and with their electric conductivity type. Different temperature behavior of the intensity of four specified Gaussian-lines was revealed for semiconductor films. In the case of insulating Pr0.8Sr0.2MnO3 samples, the intensity of three specified Gaussian lines changes with the temperature in the same way as the magnetization changed. It was established that the lanthanide (La, Pr) type does not affect the MCD spectra shape for the films with the same electrical conductivity type. Besides, the correlation between the MCD data of the films and their conductivity type was revealed. Due to the detailed analysis of the specified Gaussian lines with taking into account the well-known in the literature absorption bands, lying outside the studied spectral region, the MCD bands for the studied manganite films have been identified with electronic transitions of a different nature.

Заглавие : Current channel switching in the manganite-based multilayer structure
Место публикации : J. Phys. Conf. Ser. - 2010. - Vol. 200, Is. SECTION 5. - ISSN 17426588 (ISSN), DOI 10.1088/1742-6596/200/5/052031

Аннотация: The transport properties of the structure La0.7Sr 0.3MnO3/depleted manganite layer/MnSi have been studied. The depleted manganite layer serves as a potential barrier between the ferromagnetic conducting La0.7Sr0.3MnO3 and MnSi layers by forming a magnetic tunnel junction. The study in the CIP (current-in-plane) geometry has revealed the effect of current channel switching between the manganite layer and the manganese silicide layer with higher conductivity. The effect is controlled by bias current, magnetic field, and optical radiation. Such switching is responsible for the features of the transport properties and the magnetoresistive and photovoltaic effects in the structure. © 2010 IOP Publishing Ltd.

Аннотация: For La1-xSrxMnO3 powders prepared by the solid-phase reaction method using various thermal regimes and x values, the temperature dependences of magnetization, circular magnetic dichroism (MCD), and diffuse reflectance spectra were studied. The powders synthesis at temperatures of 800–900 °C for 2 h leads to the formation of a multiphase state. The higher temperatures and duration of synthesis lead to the formation of two predominant magnetic phases with the Curie temperature (TC) of about 250 and 360 K. Correlation is established between magnetic states of the powder and the shape of the diffuse reflection spectra. The strong red shift of the MCD spectrum for the La1-xSrxMnO3 powder is revealed comparing to the MCD spectra of La1-xSrxMnO3 films available in literature.

Аннотация: A topical and highly promising aspect of the field of spintronics is the physics involved in the flow of a spin-polarized current through magnetic tunnel structures. This review focuses on manganite-based structures, which are appealing for their high Curie temperature, highly spin-polarized conduction electrons, high chemical stability, and well-developed fabrication technology. Particular emphasis is placed on some novel approaches to studying the tunnel structures, including the use of planar geometry and the application of combined external factors (microwave and optical radiation) to investigate spin-polarized transport.

Аннотация: We demonstrate that a magnetic tunnel structure irradiated by microwaves can generate a typical voltage signal due to the rectification effect. We performed measurements in current-in-plane geometry when a current flows parallel to the interfaces in the structure. The value of the microwave-induced voltage strongly depends on the bias current and can be driven by a magnetic field. The rectification effect is discussed both in classical terms of nonlinearity of the current-voltage characteristics and within the mechanism involving the interplay between the spin-polarized current and the magnetization dynamics in the magnetic tunnel structure.
