The phase transition behavior of perovskite-type compounds, La1-xSrxCrO3, was investigated by differential scanning calorimetry, measurement of do magnetic property and X-ray diffraction at regulated temperatures. The phase diagram of La1-xSrxCrO3 has been established, which includes four phases, paramagnetic orthorhombic, canted antiferromagnetic orthorhombic, canted antiferromagnetic rhombohedral and paramagnetic rhombohedral. It was also revealed that magnetic properties such as residual magnetization (Mr) and coercive force (Hc) were affected by the variation of crystal structure from orthorhombic to rhombohedral. It was suggested that decrease of deviation of Cr-O-Cr angle from 180° by the structural phase transition decreased Mr and Hc observed in La1-xSrxCrO3 with x larger than 0.11.
