Abstract

First principles calculations using the full-potential linearized augmented plane wave method including intra-atomic noncollinear magnetism have been performed to determine the magnetic structures of RuSr2GdCu2O8. The magnetism clearly arises from the RuO6 octahedra where the moments on neighboring Ru sites order antiferromagnetically but cant perpendicular to the antiferromagnetic (AFM) axis - and so induce a weak ferromagnetism. The projected Ru moments along the AFM and FM axes result in magnetic moments of 1.16 and 0.99 μB, respectively. The results are consistent with the possible coexistence of canted ferromagnetism and superconductivity in the RuSr2GdCu2O8 - inferred from experiments.
