More Mn : New perovskite oxides (In 1− y Mn y )MnO 3 (1/9≤ y ≤1/3, see picture) were prepared by using a high‐pressure technique. The A site is doped with Mn 2+ ions, and (In 1− y Mn y )MnO 3 is similar to (Lu 1− y Ca y )MnO 3 . The B‐site‐ordered structure is realized through the ordering of Mn 3+ and Mn 4+ ions. Materials with y ≤0.25 demonstrate spin‐glass‐like properties, while (In 2/3 Mn 1/3 )MnO 3 shows magnetic properties typical for canted antiferromagnets.
