Dynamical properties of (As/sub 0.40/S/sub 0.60/)/sub 99/Mn/sub 1/ glass deduced from specific heat and magnetic measurements

Specific heat and magnetic measurements on As/sub 0.40/S/sub 0.60/ and (As/sub 0.40/S/sub 0.60/)/sub 99/Mn/sub 1/ glass alloys in the temperature range from 2 K to 200 K are presented. In the low-temperature range the glass alloys (As/sub 0.40/S/sub 0.60/)/sub 99/Mn/sub 1/ appear to be spin glass state with the temperature freezing T/sub F/=28 K.<
