摘要
The critical behaviour of a ferromagnet with dominant isotropic exchange interaction, dipolar interaction, and uniaxial anisotropy ropy is studied within the framework of the renormalized field theory up to the one-loop order. The effective critical exponent for the susceptibility gamma(eff) is calculated fro the special case of equal strengths of dipolar and anisotropy coupling constants. Recent experimental results on Fe14Nd2B are discussed in view of the theoretical progress reported here.
