抄録

The phase transition behavior of perovskite-type compounds, La<SUB>1-x</SUB>Sr<SUB>x</SUB>CrO<SUB>3</SUB>, was investigated by differential scanning calorimetry, measurement of do magnetic property and X-ray diffraction at regulated temperatures. The phase diagram of La<SUB>1-x</SUB>Sr<SUB>x</SUB>CrO<SUB>3</SUB> 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 (<I>M</I><SUB>r</SUB>) and coercive force (<I>H</I><SUB>c</SUB>) 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 La<SUB>1-x</SUB>Sr<SUB>x</SUB>CrO<SUB>3</SUB> with <I>x</I> larger than 0.11.
