Defect-induced magnetic structure of CuMnSb
Original language description
The observed ground state for the CuMnSb alloy is the antiferromagnetic (111) phase. Ab initio total energy calculations for CuMnSb contradict this result and indicate that other magnetic structures can have their total energies lower. Heusler alloys usually contain various defects depending on the sample preparation. We investigated magnetic phases of CuMnSb assuming the most common defects. The full-potential supercell approach and a Heisenberg model approach are adopted. The results of the total energy supercell calculations indicate that defects that bring Mn atoms close together promote the antiferromagnetic (111) structure already for a low critical defect concentrations (3%). A detailed study of exchange interactions between Mn moments further supports the above stabilization mechanism. The present refinement structure analysis of the neutron scattering experiment supports theoretical conclusions.
