Abstract [en]

The temperature dependence of the magnetisation of a Cu(Mn) spin glass (T-g approximate to 57 K) has been investigated using weak probing magnetic fields (H = 0.5 or 0 Oe) and specific thermal protocols. The behaviour of the zero-field-cooled, thermoremanent and isothermal remanent magnetisation on (re-) cooling the system from a temperature (40K) where the system has been aged is investigated. It is observed that the measured magnetisation is formed by two parts: i) a temperature- and observation time-dependent thermally activated relaxational part governed by the age- and temperature-dependent response function and the (latest) field change made at a lower temperature, superposed on ii) a weakly temperature-dependent frozen-in part. Interestingly we observe that the spin configuration that is imprinted during an elongated halt in the cooling, if it is accompanied by a field-induced magnetisation, also includes a unidirectional excess magnetisation that is recovered on returning to the ageing temperature.
