Abstract
Specific heat measurements of a Cu(0.5at% Mn) spin glass are reported. It is found that the energy flow ƊE due to the aging process during three decades in time at most amounts to 0.05 % of the magnetic energy at Tg. It is suggested that the relative amplitude of this energy flow might be comparable to the relative relaxation of the field cooled susceptibility at constant temperature in the same time window.
