Distorted Perovskite with eg1 Configuration as a Frustrated Spin System
Abstract
The evolution of spin- and orbital-ordered states has been systematically investigated for a series of insulating perovskites RMnO3 (R=La,Pr,Nd,...). RMnO3 with a large GdFeO3-type distortion is regarded as a frustrated spin system having ferromagnetic nearest-neighbor and antiferromagnetic (AF) next-nearest-neighbor (NNN) interactions within a MnO2 plane. The staggered orbital order associated with the GdFeO3-type distortion induces the anisotropic NNN interaction, and yields the unique sinusoidal and E-type ("up-up-down-down") AF ordered states in the distorted perovskites with eg1 configuration.
