Description
Summary:Magnetization of the cation-substituted CoxMn1 - xS sulfides upon cooling in zero and 100 Oe magnetic fields at the temperatures 4--300 K has been measured. Permittivity of these materials at frequencies from 1 to 100 kHz in magnetic and dc electric fields in the 100--300 K temperature range has been determined. Change in the dielectric permittivity under an external magnetic field is found to have a maximum in the temperature ranges of T1 ~ (110--120 K) and T2 ~ (230--250 K). Formation of spontaneous magnetic moment and the rise of magnetic susceptibility are revealed at the same temperatures in the CoxMn1 - xS solid solutions. Features of the magnetoelectric properties of the sulfides have been explained by orbital ordering.
