Exchange stiffness of ferromagnets

Résumé

Spin-wave and exchange stiffness constants of 22 ferromagnetic compounds have been deduced from their spontaneous magnetization, Ms, by using an improved technique. The improvement consists in utilizing the entire Ms(T) curve, up to the Curie point, rather than just its low-temperature part, with T≪TC. For 17 of the 22 ferromagnets, literature data have been used, while 5 compounds have been studied anew, on single crystals grown for the purpose.
