Stable Distribution Analysis of Internal Field Distribution in Ternary Alloy Spin Glass Systems, Au(CrFe)

抄録

Stable distribution analysis for internal field distribution was performed on 11 specimens of ternary alloy spin glass systems, Au_1−x(Cr_yFe_1−y)_x, with x=0.05 or y=0.6. Assuming two types of ⁵⁷Fe nuclei with different core polarization hyperfine fields, the internal field distribution was obtained for each alloy. Distributions of each specimen are well reproduced by stable distributions. The characteristic index in alloys with y=0.6 increases with x in the similar way to Au(Fe) alloys. This behavior is explained by the lattice effect, as proposed by Klein. On the other hand, the characteristic index in the alloys with x=0.05 does not depend on y.
