Magnetic properties and long range order parameter in B2-type CoFe alloys

Abstract Correlation between magnetic properties and the long-range order parameter have been studied for B2-type Co–Fe alloys around the equiatomic composition by means of accurate X-ray diffraction and magnetization measurements. The mean magnetic moment is well approximated by a linear form with respect to the square of the long-range order parameter for stoichiometry as well as nonstoichiometry.
