Abstract
The structure of perovskite-type La0.95Sr0.05Ga0.95Mn0.05O3−x crystals has been investigated using high-resolution X-ray powder diffraction technique in the temperature range of 298–1173 K. A phase transition from orthorhombic (Pbnm) to rhombohedral (R 3 c) has been detected near 340 K. A chevron-like configuration of ferroelastic domain structure was observed in rhombohedral La0.95Sr0.05Ga0.95Mn0.05O3−x crystal using the Laue technique. The chevron-like pattern is formed by the intersection of W-type domain walls (211), (101) and (110).
