Abstract
The low-temperature DC magnetic susceptibility of the amorphous spin glass (La70Gd30)80Au20 is studied as a function of hydrostatic pressure to 11 kbar. The spin-glass freezing temperature T0 decreases with pressure at the rate delta T0/ delta P=-14+or-5 mK kbar-1 which is opposite in sign to the effect observed in classical spin glasses like AgMn, AuFe and CuMn.
