Generation of imprinted strain gradients for spintronics
Giovanni Masciocchi, Mouad Fattouhi, Elizaveta Spetzler +7
In this work, we propose and evaluate an inexpensive and CMOS-compatible method to locally apply strain on a Si/SiOx substrate. Due to high growth temperatures and different therma…
Transport of skyrmions by surface acoustic waves
Jintao Shuai, Luis Lopez-Diaz, John E. Cunningham +1
Magnetic skyrmions in thin films with perpendicular magnetic anisotropy are promising candidates for magnetic memory and logic devices, making the development of ways to transport…
Revealing nanoscale disorder in W/CoFeB/MgO ultra-thin films using domain wall motion
Johannes Wilhelmus van der Jagt, Vincent Jeudy, André Thiaville +11
Disorder in ultra-thin magnetic films can significantly hinder domain wall motion. One of the main issues on the path towards efficient domain wall based devices remains the charac…
Absence of Walker breakdown in the dynamics of chiral Neel domain walls driven by in-plane strain gradients
Mouad Fattouhi, Felipe Garcia-Sanchez, Rocio Yanes +3
We investigate theoretically the motion of chiral Néel domain walls in perpendicularly magnetized systems driven by in-plane strain gradients. We show that such strain drives domai…
Strain-controlled Domain Wall injection into nanowires for sensor applications
Giovanni Masciocchi, Mouad Fattouhi, Andreas Kehlberger +3
We investigate experimentally the effects of externally applied strain on the injection of 180 domain walls (DW) from a nucleation pad into magnetic nanowires, as typically…
Magnetic field control of antiferromagnetic domain walls in a thermal gradient
R. Yanes, M. Rodriguez Rosa, L. Lopez-Diaz
An antiferromagnetic domain wall in a thermal gradient is found to experience a force towards colder regions upon the application of a uniform magnetic field along the easy axis. T…
Reliable magnetic domain wall propagation in cross structures for advanced multi-turn sensor devices
B. Borie, M. Voto, L. Lopez-Diaz +4
We develop and analyze an advanced concept for domain wall based sensing of rotations. Moving domain walls in n closed loops with n-1 intersecting convolutions by rotating fields,…
Domain wall motion by localized temperature gradients
Simone Moretti, Victor Raposo, Eduardo Martinez +1
Magnetic domain wall (DW) motion induced by a localized Gaussian temperature profile is studied in a Permalloy nanostrip within the framework of the stochastic Landau-Lifshitz-Bloc…
Magnetic field induced spin-wave energy focusing
Noel Perez, Luis Lopez-Diaz
Spin waves can transport both energy and angular momentum over long distances as they propagate. However, due to damping, their amplitude decreases exponentially as they move away…
Mechanisms of nonlinear spin-wave emission from a microwave driven nanocontact
Florin Ciubotaru, Alexander A. Serga, Luis Lopez Diaz +2
We present a micromagnetic study of linear and nonlinear spin-wave modes excited in an extended permalloy thin film by a microwave driven nanocontact. We show that the linear mode…
Combined frequency-amplitude nonlinear modulation: theory and applications
G. Consolo, V. Puliafito, G. Finocchio +6
In this work we formulate a generalized theoretical model to describe the nonlinear dynamics observed in combined frequency-amplitude modulators whose characteristic parameters exh…
Micromagnetic study of a spin-torque oscillator based on a magnetic nano-contact magnetized at an arbitrary angle
G. Consolo, B. Azzerboni, L. Lopez-Diaz +4
The nature of spin wave modes excited by spin-polarized direct current in a spin-torque auto-oscillator based on a magnetic nanocontact was studied by a micromagnetic simulation in…
