Single Crystal Growth and Magnetic Properties of High Oxidation State Material Ba2CoO4
Source abstract
Abstract
This study reports on the physical properties of Ba2CoO4 single crystals grown in a high pressure mirror furnace at oxygen pressures of 20 bar. Direction dependent magnetic susceptibility measurements on the single crystals below K reveal a spin direction which is parallel to the crystallographic a‐axis. Therefore, the spin structure of Ba2CoO4 has been re‐analyzed and a different magnetic structure with magnetic moments pointing mainly in a‐direction is proposed which reconciles neutron, µSR, and magnetic susceptibility measurements.
