Magnetic Properties of Mn_1−xFe_xAlGe with 0≤x≤0.10 —No Localized Magnetic Moment in Fe Atom—

抄録

Magnetic, X-ray and the Mössbauer effect measurements have been made on Mn_1−xFe_xAlGe compounds for 0≤x≤0.10. All of the compounds were single phase and chemically ordered intermetallic compounds with Cu₂Sb type structure. Over the whole concentration range, the Fe atoms were located at two different crystallographic sites and there was no magnetic moment either at site I and site II. The Mössbauer spectra did not show the Goldanskii-Karyagin effect in spite of having two dimensional exchange interaction in MnAlGe. The results are discussed in relation to the previous investigation.
