Annotation

The temperature relations of magnetization and the magnetocaloric effect of NiInFeO$_{4}$ ferrite are identified and they are compared with the analogous results for the Ni$_{0,2}$Zn$_{0,8}$Fe$_{2}$O$_{4}$ ferrite, in which the magnetic structure has a frustrated character. It is established that the diamagnetic field ions In$^{3+}$ not being magnetic vacancies, participate in indirect exchange interaction; a Neel spin ordering is observed in the investigated ferrite.
