The crystal and magnetic structure of the cation-disordered perovskites LaCo0.5Mn0.5O<sub>3</sub> and YCo0.5Mn0.5O<sub>3</sub>
The crystal and magnetic structures of LaCo[Formula: see text]Mn[Formula: see text]O 3 and YCo[Formula: see text]Mn[Formula: see text]O 3 perovskites were studied using neutron and X-ray powder diffraction techniques in the temperature range of 15–300[Formula: see text]K. The obtained structural data indicate a complete disorder of cobalt and manganese cations, resulting in an orthorhombic structure with the Pnma space group in both compounds. The temperature evolution of unit cell parameters, characteristic bond lengths and valence angles was studied for both compounds. Anomalies in the temperature behavior of the lattice parameters and oxygen octahedra distortions were observed. These anomalies are attributed to the formation of a ferromagnetic phase at [Formula: see text](1) K for YCo[Formula: see text]Mn[Formula: see text]O 3 and at [Formula: see text](1)[Formula: see text]K for LaCo[Formula: see text]Mn[Formula: see text]O 3 .
