Giant magnetoresistance of semimagnetic semiconductors and applications for magnetic field sensors

The results of a study of the structural and magnetic properties of single-crystal samples of the diluted magnetic semiconductor Hg1−xCrxSe with different concentrations of chromium ions (0<x⩽0.07) in the temperature interval 50–300 K are reported. It is found that the boundary of the existence region of the homogeneous solid solution lies at chromium concentrations x<0.05. In samples with x⩾0.05 the sharp growth of the magnetic susceptibility in the region of the phase transition temperature is due not only to a transition to a phase similar to a spin-glass phase, which is observed in all the samples studied, but also to a ferromagnetic contribution from ferromagnetic inclusions of HgCr2Se4 and CrSe in those samples.
