Abstract

The value of uniaxial magnetocrystalline anisotropy constant K_U in the L1₀)-type Fe₄₈Pd₅₂ single crystal is 2. 5 × 10⁷ erg cm^-3 at 4.2 K. The magnetocrystalline anisotropy decreases with increasing temperature. The temperature dependence of K_U is described by the l(l + 1) power law for a uniaxial system. The longitudinal magnetostrictions in the L1₀ phase are anisotropic. The value of λ_∥a along the a-axis in the L1₀ phase is about 100 × 10^-6 and larger than that of λ _∥100 along the 〈0 0 1〉 direction in the disordered phase and also λ_∥c along the c-axis in the L1₀ phase.
