Abstract
First-principles magnetocrystalline anisotropy energy calculations for FCC Co and Ni strained uniaxially along the [001], [001] and [111] directions, have been performed to evaluate their phenomenologically defined anisotropy and magnetoelastic constants. In the cubic limit, the calculated magnetoelastic coupling constant B1 of Co and B2 of Ni agree well with experiments. The calculated Co B1 and B2 show a pronounced dependence on both the strain size and orientation whereas that of Ni remain almost constant in the strain region below 2.5%.
