Abstract: This paper reports on the first study of the magnetic properties of polycrystalline films of CoCr$_2$O$_4$ and CoFe$_{0.5}$Cr$_{1.5}$O$_4$ multiferroics. The study covered, in particular, magnetization reversal curves and temperature dependences of the magnetization at temperatures ranging from 4.2 to 300 K in magnetic fields of up to 10 kOe. It has been shown that the Curie temperature and the pattern of the temperature dependence of the magnetization depend on the cation composition of the multiferroic. The temperature dependence of the magnetization of polycrystalline CoCr$_2$O$_4$ films has revealed an anomaly in the temperature range 10–70 K.
