The in situ behavior of distorted perovskite La 0.5؊x Bi x Ca 0.5 MnO 3 (x ؍ 0.1, 0.15, 0.2) under high pressure has been studied by energy-dispersive X-ray di4raction in a diamond anvil cell. An abnormal change of the 202+040 d-spacing ascribed to the disappearance of the distortion mode Q 2 in t
A new relaxor type n = 2 Aurivillius oxide material, Bi 2 La 0.5 Sr 0.5 Nb 1.75 Sc 0.25 O 9 (I), containing heterovalent A and B site cations was synthesized by standard solid-state reaction. The crystal structure of I was determined by Rietveld refinement of the powder X-ray diffraction data in the
