| Abstract: | We have measured the curvature of an amorphous metallic ribbon (alloy Fe72.5 Cr6.5 P13.2 C7.8) as a function of time for several annealing temperatures. The change in curvature is due to different structural relaxations of the two sides of the ribbon. The data lead to a rather narrow distribution of activation energies, centered around Eeff ∼ 1.0 eV and to a limit frequency in the range 3.103–3.105 Hz, which is discussed at the light of previous magnetic studies. |
