Abstract
Previous studies of the magnetic susceptibility of a Ag-3 at.% Mn spin-glass under high pressure are extended to include the systems Au-3at.% Mn, Cu-3at.% Mn and Au-3at.% Fe. In all four alloys the spin-glass freezing temperatureT 0 increases with pressure, yielding the volume dependences ∂ lnT 0/∂ lnV=−3.6±0.4, −4.1±0.6, −2.1±0.4 and −1.64±0.25, respectively. These results give information about the nature of the interaction mechanisms responsible for the spin-glass freezing phenomena. The pressure dependence of the Curie temperature of ferromagnetic Au-20at.% Fe was also studied.

The purity of the Cu−Be alloy was such that its magnetic susceptibility remains diamagnetic over the entire temperature range above 0.5 K
The pressure was determined using the expression ∂T c /∂P=−(0.361±0.005) K/GPa for Pb from: Clark, M.J., Smith, T.F.: J. Low Temp. Phys.32, 495 (1978)

To calculate the volume derivative from the measured pressure dependence ofT 0 one applies the expression ∂ lnT 0/∂ lnV =−(1/KT 0)(∂T 0/∂P), where the following expressions for the compressibility of the pure host elements from Gschneidner, K.A., Jr.: Solid State Phys.16, 275 (1964) withP in GPa are used: (Ag)K=−9.74×10−3 P+3.30×10−5 P 2; (Cu)K= −7.49×10−3 P+2.018×10−4 P 2; (Au)K=−5.664×10−3 P +8.05×10−5 P 2
