Abstract

The discovery of novel structural and physical properties in the A-site ordered manganite RBaMn₂O₆ (R = Y and rare earth elements) has demanded new comprehension about perovskite manganese oxides. In the present study, the A-site disordered form R_0.5Ba_0.5MnO₃ was successfully synthesized and compared with RBaMn₂O₆ in the structures and electromagnetic properties. R_0.5Ba_0.5MnO₃ has a primitive cubic perovskite cell. Unexpectedly the magnetic glassy states are dominant as the ground state for R_0.5Ba_0.5MnO₃. A peculiar behavior, the steplike ultrasharp magnetization and resistivity change, has been observed in Pr_0.5Ba_0.5MnO₃.
