%X The disaccommodation (DA) measurements of initial susceptibility were per- formed in amorphous Fe_(90-x)Ni_xZr_(10)(x=10, 20, 30) alloys. The DA was measured for two dif- ferent amorphous states: as--quenched and pretreated at 537 K for 45 min. For all the as--quenched samples, in the isochronal spectra of DA a well defined relaxation peak around 350 K is accompanied by a small but distinct peak near the Curie temperature of Fe_(90)Zr_(10) Phase (T_c=230 K). The reversibility and annealing effect on DA are analyzed within the framework of two--level model. The fits of the theory to the experimental data of reversible relaxation pro- cesses gave a spectrum of activation energies and pre--exponential factor.
