The Specific Heat of Spin Glass in PtMn Dilute Alloys

The specific heat of 1.0, 2.0 and 2.6 at.% PtMn dilute alloy has been measured. At low temperatures the magnetic specific heat increases in proportion to temperature and the proportionarity constant decreases with the Mn concentration. The specific heat curve is concave at the lowest temperatures, which is remarkably seen for 2.6 at.% PtMn dilute alloy. The curves of specific heat are in good accord with the computer simulation result taking account of the elementary excitation by Walker and Walstedt.
