Abstract
Measurements of the specific heat of seven Au1-xFex solid-solution alloys in the concentration range 0.14<x<0.28 and in the temperature range between 1.5 and 18K are reported. The anomalously high electronic-magnetic specific heat of the alloys that occurs when their Fe concentration is near the percolation limit ( approximately 16% Fe) is interpreted as arising in part from excitations in finite magnetic clusters that contain a significant fraction of the iron moments.Keywords
