Abstract:
Magnetic properties of first obtained polycrystalline films of FeCr$_2$O$_4$, CoCr$_2$O$_4$, and CoFe$_{0.5}$Cr$_{1.5}$O$_4$ multiferroics and films of a Cr$_2$O$_3$/CoFe$_2$O$_4$ composite multiferroic have been studied. In particular, magnetization curves and temperature dependences of the magnetic moment of the samples were measured in the temperature range 4.2–300 K in fields of up to 10 kOe. It was shown that the Curie point of a multiferroic depends on its cation composition. It was found that an exchange bias of the hysteresis loop exists in films of the Cr$_2$O$_3$/CoFe$_2$O$_4$ composite multiferroic at temperatures below the Néel point of Cr$_2$O$_3$ (330 K).
