TmMnO3 (x = 0) prepared at ambient pressure was hexagonal. Hexagonal and orthorhombic phases coexisted in TmMn1−xCoxO3 for 0 ≤ x < 0.5. We obtained almost single-phase orthorhombic samples with 0.5 ≤ x ≤ 0.9 using complex polymerization. Ferromagnetic orthorhombic TmMn1−xCoxO3 formed upon Co doping. The ionic states of Tm, Mn, and Co were determined through magnetization measurements. The rapid decrease in magnetization for 0.5 ≤ x ≤ 0.7 below about 25 K was explained using a model consisting of a combination of ferromagnetic Mn–Co and paramagnetic Tm sublattices.}, title = {Effect of Co Doping on the Structure and Magnetic Properties of TmMn1-xCoxO3}, volume = {87}, year = {2018}, yomi = {サカツメ, ヤスノリ and オオスギ, シュンスケ and アマカイ, ユウスケ and タカノ, ヒデアキ} }
