Abstract

The structure and magnetic ordering of bulk TbMn_0.5Cr _0.5O₃ was revealed through bulk magnetization and neutron diffraction measurements, and first-principles calculations, respectively. G-type antiferromagnetic ordering of Mn³⁺ and Cr³⁺ moments was observed in the neutron diffraction data below Néel temperature T_N ∼ 84 K. In addition, below ∼40 K, short-range magnetic ordering was identified correlating to a ferromagnetic component due to the canting of the moments along the c-axis. The spin configuration is consistent with the first-principles calculations. The magnetic structure revealed in the present TbMn_0.5Cr_0.5O₃ sample is distinct from that observed for both end members TbMnO₃ and TbCrO₃.
