Abstract

Magnetocrystalline anisotropy constant K2 is found to produce significant effects on the magnetization and magnetostriction behaviors of Terfenol-D crystals through magnetic domain rotation mechanism. Such effects have often been neglected in previous studies. Considering different values of K2 in the magnetization rotation of 〈 111 〉 easy-direction domains under external magnetic field and compressive uniaxial stress applied along [112] direction, it is shown that a change in K2 causes significant changes in both magnetization and magnetostriction curves. Therefore, K2 is an important parameter that must be considered in magnetoelastic behaviors of Terfenol-D.
