- 論文の詳細を見る
The transverse dynamical spin susceptibility 7 "(q, co) of Ni.MnSn is cat-culated within RPA with use of the energy values and the wave functions de-termined by the T.B.-OPW method and the spin wave spectra are evaluated.The effective exchange ittteraction Cfj7' is introduced as only one parameter.The correspondence between theoretical results and experimental ones is fairlygood. It is evaluated how the correlation between the spin density of d-electronsof Mn and that of condttction electrons changes with increasing q in comparisonto the cases of Cu.MnAl and Pd.MnSn obtained before. The spin wave excita-lions of NizMnSn are investigated by examining the relation between spin waveexcitations and Stoner ones.
