Abstract
We propose an indirect way of studying the fluctuation-dissipation relation in spin-glasses that only uses available susceptibility data. It is based on a dynamic extension of the Parisi-Toulouse approximation and a Curie-Wei ss treatment of the average magnetic couplings. We present the results of t he analysis of several sets of experimental data obtained from various samp les.
