Abstract
Mössbauer measurements in a-(Fe0.765Mn0.235)78Sn2Si6B14 have been performed with57Fe and119Sn. Both hyperfine fields show a “kink” near 70 K, indicating a freezing of the transverse spins. The ratio of the two hyperfine fields contains information about the correlation of the transverse spins. The ratioB hf(Sn)/B hf(Fe) stays constant aboveT xy and rises belowT xy . This indicates an alignment of the transverse spins on a local scale, as was also found inAuFe and a-FeZr.
