Abstract
The magnetic property of supersaturated Fe20Co30 Cu50 solid solution, prepared by mechanical alloying, has been investigated by using magnetometry, Mossbauer spectroscopy and inelastic neutron scattering measurements. Magnetization measurement of the alloy could be analysed by ferromagnetism only. However, Mossbauer spectroscopy and inelastic neutron scattering experiment showed that not only a ferromagnetic phase but also a paramagnetic phase of about 12% coexisted in the alloy. Spin wave stiffness constant obtained from the analysis of the temperature dependence of magnetization was similar to the value obtained from analysis of inelastic neutron scattering experiment
