Mu(+) SR in amorphous spin glasses Pd(75)Fe(5)Si(20) and Pd (75)Fe(5)P(20).

The zero-field muon spin relaxation function G(zz)(t) has been measured as a function of reduced temperature t=T/T(g) in the amorphous metallic spin glasses Pd(75)Fe(5)Si(20) and Pd(75)Fe (5)P(20). The results are in qualitative agreement with earlier measurements on dilute alloy spin glasses, including an onset of static order below T(g) and a [t/(t-1)](2) dependence of the correlation time tau(c) above T(g). Both samples have the same tau(c)(t) above T(g) and almost identical static width DELTA(s) -> DELTA(o)(-43 mu s (-1)) as T -> 0, but the t-dependence of DELTA(s) near T(g) differs markedly.
