Description
Summary:The magnetic superconductor UCoGe is analyzed with an electronic structure package, spin-orbit coupling and intra-atomic repulsion (via Hubbard UH) were included. The possibility of an antiferromagnetic configuration is studied, but it is found to be unstable, also the non-collinear magnetization seems to be ruled out. The magnetization is given mainly by the Co-atoms with M 0.6 μB/f.u. The U-atoms have two magnetic moments; M 0.07 and 0.32 μB/f.u. arranged in an alternated planes along the b-direction forming magnetic stripes.
