摘要

Magnetostriction coefficients of ordered BeFe alloys were investigated, using the first-principles full-potential linearized augmented plane-wave method. A giant magnetostriction coefficient (～1060 ppm) was predicted in the Fe_(0.8125)Be_(0.1875)alloy. We elucidated the origin of giant magnetostriction coefficient in terms of electronic structures and their responses to the tetragonal lattice distortion.
