摘要：
Within the molecular held theory, magnetic phase diagrams for a two-sublattice ferrimagnet with one unstable magnetic subsystem are determined. A detailed analysis is given for the experimental magnetization curve for the f-d ferrimagnet Y0.75Tm0.25(Co0.88Al0.12)(2) measured up to 38 T at 4.2 K in which two metamagnetic transitions and a non-collinear phase between them are observed.
