摘要

The effect of substitution of chromium for zinc on the microstructure and magnetotransport properties of solid solution MnZn1–XCrXSb (0 ≤ X ≤ 0.2) samples with a tetragonal Cu₂Sb-type structure was studied by impedance spectroscopy. It has been established that substitution of chromium for zinc increases the real impedance component and the inductive contribution to the impedance at some frequency is prevailed. The observed decrease in the AC electrical resistance and impedance in a magnetic field has been explained by suppression of electron spin scattering by localized magnetic moments of chromium ions. A change in the magnetoresistance and magnetoimpedance sign depending on frequency and temperature has been found and the frequency and temperature ranges corresponding to the maximum magnetoimpedance value–10% at T = 80 K (X = 0.05), and − 6.5% at T = 300 K (X = 0.15) have been determined. The effects observed in the MnZn1-XCrXSb compounds demonstrate their potential for use in high-frequency spintronics and sensors.
