| Abstract: | The zero-field muon spin relaxation functionG zz (t) has been measured as a function of reduced temperaturet=T/T g in the amorphous metallic spin glasses Pd75Fe5Si20 and Pd75Fe5P20. The results are in qualitative agreement with earlier measurements on dilute alloy spin glasses, including an onset of static order belowT g and a t/(t-1)]2 dependence of the correlation time τc aboveT g. Both samples have the same τc (t) aboveT g and almost identical static width ΔS→Δo?43 μS?1) asT»0, but thet-dependence of Δs nearT g differs markedly. |
