Abstract
ErNi5-xCox alloys were prepared by RF induction melting and analyzed u sing neutron powder diffraction. Rietveld analysis of neutron diffract ion data indicates that the unit cell volume increases with Co content while the a and c lattice parameters show different dependencies on t he composition. The Co atoms show higher affinity for the 3g sites tha n for the 2c sites. The Co sublattice tends to couple antiferromagneti cally to the Er sublattice. The easy magnetization direction is along the c axis.
