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…
Influence of magnetic field and ferromagnetic film thickness on domain pattern transfer in multiferroic heterostructures
Diego López González, Arianna Casiraghi, Florian Kronast +2
Domains in BaTiO induces a regular modulation of uniaxial magnetic anisotropy in CoFeB via an inverse magnetostriction effect. As a result, the domain structures of the CoFeB w…
Electric-field-driven domain wall dynamics in perpendicularly magnetized multilayers
Diego López González, Yasuhiro Shirahata, Ben Van de Wiele +4
We report on reversible electric-field-driven magnetic domain wall motion in a Cu/Ni multilayer on a ferroelectric BaTiO substrate. In our heterostructure, strain-coupling to f…
Influence of elastically pinned magnetic domain walls on magnetization reversal in multiferroic heterostructures
Arianna Casiraghi, Teresa Rincón Domínguez, Stefan Rößler +6
In elastically coupled multiferroic heterostructures that exhibit full domain correlations between ferroelectric and ferromagnetic sub-systems, magnetic domain walls are firmly pin…
Piezoelectric strain induced variation of the magnetic anisotropy in a high Curie temperature (Ga,Mn)As sample
A. Casiraghi, A. W. Rushforth, J. Zemen +5
We show that effective electrical control of the magnetic properties in the ferromagnetic semiconductor (Ga,Mn)As is possible using the strain induced by a piezoelectric actuator e…
Tuning perpendicular magnetic anisotropy in (Ga,Mn)(As,P) by thermal annealing
A. Casiraghi, A. W. Rushforth, M. Wang +8
We have investigated the effects of post growth low temperature annealing on the magnetic, electrical and structural properties of (Ga_0.94,Mn_0.06)(As_0.9,P_0.1) layers grown by m…
