Abstract
The spin wave spectrum in a combined system of itinerant electron spins and localised spins is calculated. Spin waves with wavevector q propagating in itinerant electrons and those propagating on localised spins are coupled together by the exchange interaction between the itinerant electrons and the localised spins. Acoustical and optical modes appear at qqc and they decay with a life time. The spin wave spectrum observed by Holder (1976) for an ordered ferromagnetic Pd3Fe alloy can be well explained by the present calculated results.Keywords
