 Magnetization, ac and dc magnetic susceptibility measured in the zero-field-cooled mode were used to study the high spin-low spin transitions in polycrystalline Cu0.2Co0.76Cr1.83Se4 semiconductor. The real part component of fundamental susceptibility χ1' (T) and its second (χ2) and third (χ3) harmonics revealed two spectacular peaks at 128 K and at 147 K, confirming the appearance of the spin-crossover phenomenon.
