M. Ipatov, V. Zhukova, A. K. Zvezdin, and A. Zhukov Two magnetization reversal regimes were found in magnetically bistable Fe-rich microwires. The first one, exhibiting an almost linear dependence of the domain wall velocity v on magnetic field H reaching 1.7 km/s, is related to single DW propagation. The second essentially nonlinear regime is observ ... [J. Appl. Phys. 106, 103902 (2009)] published Mon Nov 16, 2009. (Source: Journal of Applied Physics)
