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.
