Description

Giant intrinsic magnetic hardness is found at low temperatures in structurally homogeneous materials SmNi/sub 5-x/Cu/sub x/. Magnetic hardness peaks at a composition SmNi/sub 2.5/Cu/sub 2.5/ where the crystal field disorder due to compositional randomization is at a maximum. By comparison with SmCo/sub 5-x/Ni/sub x/, where giant intrinsic magnetic hardness originates, in part, from fluctuations from site to site of the magnitude of moment and strength of exchange of the transition metal, magnetic hardness in the SmNi/sub 5-x/Cu/sub x/ is predominantly due to anisotropy and concomitant exchange fluctuations on Sm sites
