Structural and magnetic characterization of NdFe/sub 10.2-x/Co/sub x/Mo/sub 1.8/

摘要

Alloys of the title formula are studied by powder X-ray and neutron diffraction, magnetic susceptibility and magnetization in fields up to 8 T. The Curie temperature has a maximum for x=7. For x>3 the anisotropy is conical at room temperature. At lower temperatures a spin reorientation to planar and at higher temperatures to axial alignment takes place. For x/spl ges/5 anisotropies are axial for all the alloys temperatures. A phase diagram is proposed.
