Here, we present the study on the influence of the Ni content on the magnetization processes of the amorphous glass-coated Fe77.5-x NixSi7.5 B15 (x = 0-40) microwires. Measurement of the amplitude dependence of the complex susceptibility was used to observe the magnetization process. It is shown that the magnetization process in the presented samples runs mainly through the domain wall motion.
