Abstract. In this paper, based on the results of experimental studies of the behavior of magnetic phases of partially substituted rare earth ferrite garnets (BiYLu)3(FeGa)5O12 and (BiGd)3(FeGa)5O12 near the magnetic compensation point in strong magnetic fields, a phenomenological model is proposed that explains the behavioral features of the non-collinear phase based on taking into account the paraprocess, that is, the mutual influence of the spin-reorientation phase transition and the Curie point.
Key words: mixed ferrite garnets, compensation temperature, sublattice magnetization.
Financing: The study was carried out as part of the State Task of Kotelnikov Institute of Radio-Engineering and Electronics of Russian Academy of Science, theme FFWZ-2024-007.
