Effect of transverse magnetic field on domain wall propagation in magnetically bistable glass-coated amorphous microwires

We experimentally studied domain wall (DW) propagation in amorphous Fe69Si10B15C6 and Co56Fe8Ni10Si11B16 microwires. We found that, in some cases, application of transverse magnetic field increases DW velocity in studied microwires. This effect is explained considering effect of transverse magnetic anisotropy on DW propagation. Considerable increase of DW velocity has been observed at enhanced longitudinal magnetic field, H. Such abrupt increasing of DW velocity can be related with defects contribution.
