Abstract
Perovskite-like compounds with the general formula La1 - x Bi x Mn1 - y M y O3 + (M = Fe, Ni, Cu; x = 0.1-0.3; у = 0.0-0.2, х = у = 0.1) were obtained by solid-phase synthesis and characterized by means of XPA, TG and dilatometry. For solid solutions with rhombohedral structure, the existence of two regions in the linear dependence of unit cell volume on temperature was explained by thermal expansion of samples.
