- Abstract
Magnetic properties of first obtained polycrystalline films of FeCrO, CoCrO, and CoFeCrO multiferroics and films of a CrO/CoFeO 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 CrO/CoFeO composite multiferroic at temperatures below the Néel point of CrO (330 K).
