Inorganic compounds composed of low-dimensional ferromagnets exhibit fascinating properties and provide a rich opportunity to investigate the ferromagnetic states, phase transitions, magnetic transitions and magnetization phases. Among them, BaFe2(PO4)2 (BFPO), which is a two-dimensional ferromagnetic material, has a special structural and magnetic structure at low temperature. Anomalous distortion at about 150K causes a structural phase transition from rhombohedral(R ) to triclinic(P ). However, further cooling results in a magnetic phase transition from paramagnetic to ferromagnetic at about 80K, and at the same time, it returns to the original rhombohedral(P →R ). The change of structural phase transition and the change of band gap in the sintering process of BFPO. This study could be a preliminary study on the fabrication of ceramic targets for thin film deposition of BFPO.
