Domain wall dynamics in a single CrO_2 grain

Recently we have reported on the magnetization dynamics of a single CrO_2 grain studied by micro Hall magnetometry (P. Das et al., Appl. Phys. Lett. \textbf{97} 042507, 2010). For the external magnetic field applied along the grain's easy magnetization direction, the magnetization reversal takes place through a series of Barkhausen... Show more
