    The magnetic specific heat of ZnCoSe data are reported in the temperature range 1.5 <T <50 K and magnetic field B <3 T. The experimental data are interpreted in the Extended Nearest Neighbour Pair Approximation taking into account short and long ranged d-d exchange interaction

    Hopping Conductivity in (Zn,Fe)Se Intentionally Doped with Ag

    No full text
    The transport phenomena in (Zn,Fe)Se were studied. In order to obtain iron centers in Fe3+\text{}^{3+} charge state the crystals were doped by Ag what produces acceptors compensating Fe2+\text{}^{2+} donors. The results are explained in terms of thermally activated jumping of charges between Fe3+\text{}^{3+} and Fe2+\text{}^{2+} centers. The nature of activation energy is discussed. The polaron model seems to be not valid in our case. The Coulomb interaction between charged acceptors and "holes" on iron centers is considered as the origin of thermal activation of jumps. We suggest the deviation from random and mutually independent distributions of charged Ag acceptors and Fe3+\text{}^{3+} ions resulting from the electrostatic interactions between them at high temperatures

    Magnetic Anisotropy of V++\text{}^{++} in CdS

    No full text
    The magnetization measurements at magnetic field up to 6 T obtained from newly grown hexagonal Cd1βˆ’x\text{}_{1-x}Vx\text{}_{x}S (x β‰ˆ 0.0004) are presented. The strong anisotropy of magnetization is observed at low temperatures (1.6 < T < 20 K). The data are well described by the crystal field model calculations taking into account static trigonal Jahn-Teller distortion and spin-orbit coupling
