Abstract
Bulk magnetization measurements were made between 5 and 300 K in fields up to 14 kOe on a series of iron-chromium alloys containing from 2- to 70-at.% Cr. The temperature dependence of the magnetization was analyzed to yield spin-wave stiffness coefficients that are systematically different from values obtained directly by inelastic-neutron-scattering measurements. The concentration dependence of the mean moment is approximately linear and is close to the Slater-Pauling curve. However, subtle deviations from linearity reflect the concentration dependence of the individual iron and chromium moments, which is presented in part II. The concentration dependence of the moments can be approximately reproduced by existing coherent-potential-approximation calculations.This publication has 25 references indexed in Scilit:
