SYNTHESIS AND MAGNETIC PROPERTIES OF CoCuCrS (x = 0–0.6) SOLID SOLUTIONS

Solid solutions CoCuCrS (x = 0–0.6) between ferrimagnet CoCrS (T = 222 K) and ferromagnet CuCrS (T = 367 K) were synthesized by the solid-phase method. Magnetic properties were investigated by the dynamic method in the temperature range of 5–300 K at different frequencies (100, 1000, 5000 and 10000 Hz) of an alternating magnetic field with an amplitude of 1 Oe. The temperatures and nature of magnetic phase transitions in the system were determined. Substitution of Co by Cu from x = 0 to x = 0.6 increases the magnetic ordering temperature from 222 K to 287 K, respectively. A transition to a frustrated state of the spin glass type was detected in the sample with x = 0.05.
