Abstract
Atomic short-range order in CuMn alloys (5-30 at% Mn) in equilibrium state is studied as well as its effect on the magnetic behaviour and low temperature specific heat. Spin glass features are observed and the freezing temperature Tf appears to be not sensitive to SRO as well as the linear specific heat term γ*T whereas the amplitude of the susceptibility peak at Tf is drastically increased.
