Study of the single domain-wall structure in glass-coated microwires

We present the complex study of the domain-wall structure in glass-coated microwires using different methods based on the application of transversal and circular magnetic fields. The results can be understood in terms of two possible structures of domain walls being transversal at low fields and vortex at high fields. Moreover, it is shown that a vortex domain wall does not nucleate at the beginning of propagation, but it is transformed from a transversal domain wall after its depinning.
