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 Cu_{0.2}Co_{0.76}Cr_{1.83}Se_4 semiconductor. The real part component of fundamental susceptibility χ_1' (T) and its second (χ_2) and third (χ_3) harmonics revealed two spectacular peaks at 128 K and at 147 K, confirming the appearance of the spin-crossover phenomenon.
