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…
Measuring interfacial Dzyaloshinskii-Moriya interaction in ultra-thin magnetic films
Michaela Kuepferling, Arianna Casiraghi, Gabriel Soares +7
The Dzyaloshinskii-Moriya interaction (DMI), being one of the origins of chiral magnetism, is currently attracting considerable attention in the research community focusing on appl…
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…
Dynamics and morphology of chiral magnetic bubbles in perpendicularly magnetized ultra-thin films
Bhaskarjyoti Sarma, Felipe Garcia-Sanchez, S. Ali Nasseri +2
We study bubble domain wall dynamics using micromagnetic simulations in perpendicularly magnetized ultra-thin films with disorder and Dzyaloshinskii-Moriya interaction. Disorder is…
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…
Spin-orbit driven ferromagnetic resonance: A nanoscale magnetic characterisation technique
D. Fang, H. Kurebayashi, J. Wunderlich +7
We demonstrate a scalable new ferromagnetic resonance (FMR) technique based on the spin-orbit interaction. An alternating current drives FMR in uniform ferromagnetic structures pat…
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…
