Magnetocapacity of manganese sulphides substituted by thulium ions

The capacity and the dielectric loss tangent of a TmxMn1-xS (x=0.05, x=0.1) solid solution in the frequency range (1-300) kHz without field H=0 and in a magnetic field of H=8 kOe in the temperature range (80-500) K were measured. The increase of dielectric permittivity and the maximum of dielectric...

Summary:The capacity and the dielectric loss tangent of a TmxMn1-xS (x=0.05, x=0.1) solid solution in the frequency range (1-300) kHz without field H=0 and in a magnetic field of H=8 kOe in the temperature range (80-500) K were measured. The increase of dielectric permittivity and the maximum of dielectric losses at high temperatures were found. The shift of the maximum of the imaginary part of the permittivity towards high temperatures with increasing concentration is found. The magnetocapacitance effect for two compositions and change the sign of magnetocapacity with increasing concentration were revealed. The magnetocapacity is explained in terms of the model with orbital electron ordering.
