Abstract
The effect of Co substitution for Fe in Nd3(Fe1âxCox)27.7Ti1.3Ny (0 â¤Â x â¤Â 0.4) compounds on the magnetocrystalline anisotropy has been investigated. The anisotropy constants K's and the anisotropy field HA have been deduced from the magnetization curves measured on magnetically aligned powder (4-7 μm) samples. The obtained results show that at RT the anisotropy is uniaxial and HA (about 10 T) does not change substantially upon the substitution. At 5 K the results for K's give evidence for the presence of easy-cone-type anisotropy. The cone angle as well as the anisotropy field decrease upon the substitution from 21.6° to 11.8° and from 22.8 to 18.6 T, respectively.
