Magnetocrystalline anisotropy of R2Fe14B tetragonal compounds

Abstract
A systematic study of magnetocrystalline anisotropy of R2Fe14B tetragonal compounds with various rare-earth elements (R) has been carried out at room temperature by the pulse method. The anisotropy fields of Y2Fe14B and Nd2Fe14B compounds are 3.1 and 12 MA/m, respectively. The maximum anisotropy field of 28 MA/m was observed in Tb2Fe14B compounds. The change in lattice parameters, saturation magnetization, and the Curie temperature with the rare-earth elements of R2Fe14B compounds is also described.
