Аннотация	We present a magnetic model for an antiferromagnetic compound γ-Mn3(PO4)2, which was previously shown to exhibit a 1/3 magnetization plateau due to the trimer-based structure of the lattice of magnetic Mn2+ ions with S = 5/2. An exchange Hamiltonian that yields observed field transitions is obtained from fitting magnetization data. It is shown that both biquadratic coupling and single-ion anisotropy are necessary to be present in the magnetic model to explain multiple phase transitions in the magnetic sus- ceptibility data. The calculated magnetic spectrum is in agreement with the low-temperature specific heat data.
