Аннотация: The magnetic ground state of CuB2O4 is incommensurate at T = 1.8 K and undergoes a continuous phase transition to a noncollinear commensurate antiferromagnetic state at T* similar to 10 K. Close to T* higher-order magnetic satellites are observed. Coexistence of long- and short-range magnetic order is observed in both magnetic phases. This suggests that the association of the Dzyaloshinskii-Moriya interaction and anisotropy leads to the formation of a magnetic soliton lattice.

Аннотация: The magnetic susceptibility and magnetic resonance measurements of an amorphous compound Bi2CuO4 have been carried out. It was pointed out, that a part of Cu2+ ions stays in the paramagnetic state down to T=4,2 K. The magnitude of the effective exchange integral in amorphous Bi2CuO4 has been estimated. The magnetic resonance measurements revealed the existance of the magnetic phase transition to spin-glass state at T=100 K.

Аннотация: Single crystal and amorphous samples Bi2CuO4 were prepared. The magnetic susceptibility, magnetization, magnetic resonance and electrical resistivity measurements for wide range of temperatures and magnetic fields are presented. The anisotropic exchange interactions and 3-d antiferromagnetic behaviour were revealed for single crystal Bi2CuO4. The effective magnetic moments per copper ion were determined. The sharp differences between single crystal and amorphous samples properties were shown.

Заглавие : Magnetoimpedance, Jahn-Teller transitions upon electron doping of manganese sulfide
Место публикации : J. Magn. Magn. Mater. - 2020. - Vol. 513. - Ст.167104. - ISSN 03048853 (ISSN), DOI 10.1016/j.jmmm.2020.167104

Аннотация: The effect of a magnetic field on the electrical and magnetic properties of manganese sulfide upon electron doping in the YbxMn1−xS (0.05 ˂ x ˂ 0.2) compound has been investigated. The change in the conductivity type from the Poole–Frenkel to Mott law have been established using the I–V characteristics and the change in the carrier type upon temperature and concentration variations has been observed. The effect of the sample prehistory on the conductivity, impedance, and magnetic susceptibility under the action of a magnetic field in a wide temperature range has been found. The trivalent state of ytterbium ions has been determined using the electron paramagnetic resonance study. The dynamic JT transitions temperature are found by IR method and by the electron paramagnetic resonance. Anomalies of carrier mobility and magneto-impedance were found in the vicinity of the Jahn-Teller transitions. The experimental data are explained by the localization of electrons with the formation of the interstitial orbital momenta and an orbital momentum into the site. The sample prehistory is related to the lifting of the orbital angular moments degeneracy and the direction of the axis of distortion of the octahedrons in a magnetic field.

Заглавие : Magnetodielectric effect and spin state of iron ions in iron-substituted bismuth pyrostannate
Место публикации : Eur. Phys. J. Plus. - 2020. - Vol. 135, Is. 10. - Ст.776. - ISSN 21905444 (ISSN), DOI 10.1140/epjp/s13360-020-00781-2

Аннотация: The magnetic and magnetodielectric properties of bismuth pyrostannate Bi2(Sn1-xFex)2O7 (x= 0.1 and 0.2) have been examined. Using the Mossbauer spectroscopy and electron paramagnetic resonance, the high-spin state and crystallographic positions of iron ions have been established. The coexistence of triclinic symmetry domains in the Bi2(Sn1-xFex)2O7(x=0.1) compound with the monoclinic symmetry below 140 K has been found. For the Bi2(Sn1-xFex)2O7 composition with x= 0.2 , the nonlinear field dependence of magnetization in the paramagnetic region up to room temperatures has been observed. The electric polarization hysteresis and the magnetoelectric effect in the Bi2(Sn1-xFex)2O7 compound have been disclosed. The magnetic field-dependent anomalous behavior of magnetization has been explained by the magnetoelectric effect.
