Sažetak
Here we present the results for the influence of etching of the surfaces of the amorphous Fe73.5Cu1Nb3Si15.5B7 ribbon on its magnetic properties in amorphous state and states obtained by successive annealing for one hour at several temperatures T-a less than or equal to 450 degrees C. We discuss the changes in the domain structure, anisotropy and domain wall (DW) pinning in terms of the corresponding changes in the average angle <delta> between the domain magnetizations and ribbon axis, coercive field H-c, remanent magnetization M-r and maximum permeability mu(max). The measurements show rather weak effects of etching on the magnetization processes and DW pinning in the amorphous state (small initial decrease of H-c). Results for the successively annealed sample show that etching does not improve properties of the nanocrystallized FeCuNbSiB ribbons.
