- 論文の詳細を見る
Magnetic perovskites BiMnO_3 and BiCrO_3 were synthesized under very high pressures. There are phase transitions at 500°K and 410°K at atmospheric pressure for BiMnO_3 and BiCrO_3 respectively, and the crystal distortion of each phase was determined. BiMnO_3 is ferromagnetic below 103°K, while BiCrO_3 is inferred to be antiferromagnetic below 123°K accompanied with weak ferromagnetic moment. BiCrO_3 has an abnormally large effective Bohr magneton number at room temperature phase. The distortion of BiMnO_3 decreases slightly below the ferromagnetic Curie point.
