    Abstract

    Precise measurements of YbFeO3 magnetization in the spin-reoirentation temperature interval are performed. It is shown that ytterbium orthoferrite is well described by the modified mean-field theory recently developed for ErFeO3. This validates the conjecture about the essential influence of the rare-earth ion’s anisotropic paramagnetism on the magnetization behavior in the reorientation regions of all orthoferrites with Γ4→Γ24→Γ2 phase transitions.
