Earthquake-like dynamics in ultrathin magnetic film
Gianfranco Durin, Vincenzo Maria Schimmenti, Marco Baiesi +6
We study the motion of a domain wall on an ultrathin magnetic film using the magneto-optical Kerr effect (MOKE). At tiny magnetic fields, the wall creeps only via thermal activatio…
Bloch-to-Néel domain wall transition evinced through morphology of magnetic bubble expansion in Ta/CoFeB/MgO layers
Arianna Casiraghi, Alessandro Magni, Liza Herrera Diez +5
Ta/CoFeB/MgO trilayers with perpendicular magnetic anisotropy are often characterised by vanishing or modest values of interfacial Dzyaloshinskii-Moriya interaction (DMI), which re…
Individual skyrmion manipulation by local magnetic field gradients
Arianna Casiraghi, Héctor Corte-León, Mehran Vafaee +6
Magnetic skyrmions are topologically protected spin textures, stabilised in systems with strong Dzyaloshinskii-Moriya interaction (DMI). Several studies have shown that electrical…
Quantitative scaling of magnetic avalanches
G. Durin, F. Bohn, M. A. Correa +3
We provide the first quantitative comparison between Barkhausen-noise experiments and recent predictions from the theory of avalanches for pinned interfaces, both in and beyond mea…
Universal properties of magnetization dynamics in polycrystalline ferromagnetic films
Felipe Bohn, Marcio Assolin Correa, Alexandre Da Cas Viegas +3
We investigate the scaling behavior in the statistical properties of Barkhausen noise in ferromagnetic films. We apply the statistical treatment usually employed for bulk materials…
Loss separation for dynamic hysteresis in magnetic thin films
Francesca Colaiori, Gianfranco Durin, Stefano Zapperi
We develop a theory for dynamic hysteresis in ferromagnetic thin films, on the basis of the phenomenological principle of loss separation. We observe that, remarkably, the theory o…
