Abstract

Abstract: By adding the spin-spin dipole interaction in the convention Hamiltonian,a theoretical analysis of the experimental magnetization of rare earth compound Ho₂Co₁₄Fe₃ is performed with the aid of parameter-fitting method.It is shown that when the theoretical parameters are adequately fixed,the calculated magnetization curve is in agreement with that ofthe magnetic experiments,and the transition of magnetic moment is explained.

Key words: Magnetic properties, Exchange interaction, Spin-spin dipole interaction
