Phase Behavior and Some Properties of LaMn1-x RhxO3 Solid Solution. — The title
compounds are characterized by powder XRD, magnetic, and electrical conductivity
measurements. They crystallize in the space group Pnma at room temperature. A transformation from O'- to O-type orthorhombic structure occurs near x = 0.6. The title compounds exhibit semiconducting properties above room temperature. Compounds in the
region 0.1 ≤ x ≤ 0.9 show ferromagnetism but the substitution of Rh3+ for Mn3+ weakens the ferromagnetic interactions resulting in a decrease of the Curie temperature. —
