摘要: 57Fe Mossbauer spectra of YTi(Fe1−xMx)11 (M=Co and Ni) have been studied. The average isomer shifts increase monotonically. quadrupole splittings a sudden change for YTi(Fe1−xCox)11 between x=0.4 0.6. It appears that spin reorientation occurs over this composition range. Both hyperfine fields the three sites field at first, then decrease with increasing Co or Ni concentration. maximum is 27.7 T x=0.6 24.1 about x=0.2 YTi(Fe1−xNix)11. moments atoms are 1.3(1)μB 0.6(1)μB, respectively, obtained from formula μ = (1 − x)μFe + xμT.
