In collaboration with colleagues at the Institut Jean Lamour (Nancy), we investigated domain wall propagation in synthetic ferrimagnets under applied magnetic fields. Depending on the relative alignment of the two component layers (parallel or antiparallel), different velocity versus field regimes are observed. This behaviour results from the competition between the external applied field and the interlayer coupling. This work has just appeared in Applied Physics Letters.
