Magnetic susceptibility measurements were carried out for two hexagonal perovskite-type oxides Sr 1ุx (Mn 1ุx Ni x )O 3 with slightly di4erent compositions (i.e., x โซุโฌ 1 3 and 0.324). A signi5cant di4erence in the susceptibilities of the two phases demonstrates the need to control phase composition
The hexagonal perovskite-type oxides A x BO 3 (A โซุโฌ Ca, Sr, Ba; B โซุโฌ Co, Ni) consist of (BO 3 ) chains made up of face-sharing BO 6 octahedra and BO 6 trigonal prisms. On the basis of molecular orbital calculations for their structural building blocks we examined why the transition metal atoms in
