The type of current carriers and the influence of prehistory on the dynamic magnetic characteristics in Ho_xMn_1-xS

Abstract

In a solid solution of HoxMn1-xS, the influence of the prehistory of a sample cooled without a field and in a magnetic field on the magnetic characteristics is investigated. An increase in the inductance of a coil with a sample cooled in a magnetic field is found. The type of current carriers, the temperature of the change of the sign of the current carriers, the concentration and mobility from the Hall constant are determined. The results are explained in the model of spin and orbital-charge glass formation.
