Abstract :
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⩾5 anisotropies are axial for all the alloys temperatures. A phase diagram is proposed
