Abstract

Slowly cooled Nd1 − x BaxCoO3 − δ samples were two-phase in the concentration interval 0.3 ≤ x ≤ 0.46. One of the phases had O-orthorhombic lattice distortions (Pbnm) characteristic of ferromagnetic samples with x ≤ 0.3, and the other phase had tetragonal distortions (P4/mmm) characteristic of samples with x ≥ 0.46. Tetragonal distortions were caused by ordering of Nd3+ and Ba2+ ions. Samples with ordered neodymium and barium ions (Nd1 − y Ba1 + y Co2O6 − γ at −0.08 ≤ y ≤ 0.08) experienced metal-dielectric and orientation magnetic phase transitions.
