Abstract

The spin wave stiffness constant in Niο£ΏCu alloys is calculated in the RPA and cluster coherent potential approximation. It is shown that the stiffness constant D decreases when the concentration of Cu increases.

## Abstract Hydrogen 2__p__ orbitals have been introduced into the basis set to calculate the Fermi contact term of spin–spin coupling constants using the FPT INDO method. Different coupling constants show different sensitivity to these hydrogen polarization functions. Some improvements are found f
