概要

The dvuaamical nmasxaetic suscer>tibilit>' 2((7, ctc) of CL12MI1A1 js evaltuated onthe basis of the ?'ealistic battd stx'ucture which has beevt calculated. by Mt?e11er'shybridized T.B.-OPW xnethod. The effective exchange interactioxa Ug.," is ivatro-duced as only one paraxnetex" in the present calculation. The theoretical x'esultsof the spi?a wave spectra of Cu.MnA] are ita good agreentexct with the experixmevttalones.It turns out that the transitjo?as from the majority spina bands to the nti?xorityspin ba?ads mainly contribute to z(q, c?:;). The correlation betweetx the spin densityof d.-electrons of Mn and that of conduction electrons naainly co?ttributes to thespin waves with small q, while for the spin waves with large q, the correlationbetween those of Mn is most important.
