Barkhausen noise from precessional domain wall motion
Touko Herranen, Lasse Laurson
The jerky dynamics of domain walls driven by applied magnetic fields in disordered ferromagnets -- the Barkhausen effect -- is a paradigmatic example of crackling noise. We study B…
Multistep Bloch-line-mediated Walker breakdown in ferromagnetic strips
Johanna Hütner, Touko Herranen, Lasse Laurson
A well-known feature of magnetic field driven dynamics of domain walls in ferromagnets is the existence of a threshold driving force at which the internal magnetization of the doma…
Bloch line dynamics within moving domain walls in 3D ferromagnets
Touko Herranen, Lasse Laurson
We study field-driven magnetic domain wall dynamics in garnet strips by large-scale three-dimensional micromagnetic simulations. The domain wall propagation velocity as a function…
Domain walls within domain walls in wide ferromagnetic strips
Touko Herranen, Lasse Laurson
We carry out large-scale micromagnetic simulations which demonstrate that due to topological constraints, internal domain walls (Bloch lines) within extended domain walls are more…
