Abstract: The components of the impedance, the impedance of the Lu$_x$Mn$_{1-x}$S ($x<$ 0.2) solid solution in the temperature range of 80–500 K and the frequency of 100–10$^6$ Hz were studied. A change in the sign of the magnetoimpedance in concentration and temperature is found. The contribution of the reactive and active components to the magnetoimpedance is determined. The correlation of magnetoimpedance temperatures with the temperatures of the maximum attenuation of ultrasound and electrosound has been established. The frequency dependences of the reactive part of the impedance are described in the Cole-Cole model.

Keywords: semiconductors, impedance, magnetoimpedance, attenuation of ultrasound.
