Abstract
The magnetic after-effect in Tbx(Fe85Co15)1−x with 0.19<x<0.33 measured at different applied fields Ha and domain observations using the polar Kerr effect show that the distinct differences of the after-effect between the samples investigated correspond to differences in domain behaviour. Samples exhibiting growth of non-equilibrium domains and simultaneous formation of new nuclei with time are distinguished from samples showing instantaneous formation of all nuclei running out as stripes into an equilibrium maze-like pattern with time. The evaluation of the after-effect measurement as a function of time for one sample yields a thermally activated wall motion with a potential barrier of ≈ 100 eV and an activation volume of ≈ 1.4 × 10−4 μm3.
