Manipulation of magnetic solitons under the influence of DMI gradients
Rayan Moukhader, Davi Rodrigues, Eleonora Raimondo +6
Magnetic solitons are promising for applications due to their intrinsic properties such as small size, topological stability, ultralow power manipulation and potentially ultrafast…
A spintronic Huxley-Hodgkin-analogue neuron implemented with a single magnetic tunnel junction
Davi R. Rodrigues, Rayan Moukhader, Yanxiang Luo +6
Spiking neural networks aim to emulate the brain's properties to achieve similar parallelism and high-processing power. A caveat of these neural networks is the high computational…
Ultra-sensitive voltage-controlled skyrmion-based spintronic diode
Davi Rodrigues, Riccardo Tomasello, Giulio Siracusano +2
We have designed a passive spintronic diode based on a single skyrmion stabilized in a magnetic tunnel junction and studied its dynamics induced by voltage-controlled anisotropy (V…
Voltage-Controlled High-Bandwidth Terahertz Oscillators Based On Antiferromagnets
Mike A. Lund, Davi R. Rodrigues, Karin Everschor-Sitte +1
Producing compact voltage-controlled frequency generators and sensors operating in the terahertz (THz) regime represents a major technological challenge. Here, we show that noncoll…
Temperature gradient-driven magnetic skyrmion motion
Eleonora Raimondo, Elias Saugar, Joseph Barker +7
The static and dynamic properties of skyrmions have recently received increased attention due to the potential application of skyrmions as information carriers and for unconvention…
Nonzero Skyrmion Hall Effect in Topologically Trivial Structures
Robin Msiska, Davi R. Rodrigues, Jonathan Leliaert +1
It is widely believed that the skyrmion Hall effect, often disruptive for device applications, vanishes for overall topologically trivial structures such as (synthetic) antiferroma…
Current-induced H-shaped-skyrmion creation and their dynamics in the helical phase
Ross Knapman, Davi R. Rodrigues, Jan Masell +1
Inevitable for the basic principles of skyrmion racetrack-like applications is not only their confined motion along one-dimensional channels but also their controlled creation and…
Spin-wave driven bidirectional domain wall motion in kagome antiferromagnets
Davi R. Rodrigues, Akshaykumar Salimath, Karin Everschor-Sitte +1
We predict a mechanism to controllably manipulate domain walls in kagome antiferromagnets via a single linearly polarized spin-wave source. We show by means of atomistic spin dynam…
Nonlinear dynamics of topological ferromagnetic textures for frequency multiplication
Davi R. Rodrigues, Jonas Nothhelfer, Morteza Mohseni +3
We propose that the non-linear radio-frequency dynamics and nanoscale size of topological magnetic structures associated to their well-defined internal modes advocate for their use…
Facilitating domain wall injection in magnetic nanowires by electrical means
Davi R. Rodrigues, Nils Sommer, Karin Everschor-Sitte
We investigate how to facilitate the injection of domain walls in chiral ferromagnetic nanowires by electrical means. We calculate the critical current density above which domain w…
Spin-transfer torque-driven motion, deformation, and instabilities of magnetic skyrmions at high currents
Jan Masell, Davi R. Rodrigues, Ben F. McKeever +1
In chiral magnets, localized topological magnetic whirls, magnetic skyrmions, can be moved by spin polarized electric currents. Upon increasing the current strength, with prospects…
Chiral excitations of magnetic droplet solitons driven by their own inertia
M. Mohseni, D. R. Rodrigues, M. Saghafi +7
The inertial effects of magnetic solitons play a crucial role in their dynamics and stability. Yet governing their inertial effects is a challenge for their use in real devices. He…
Characterizing breathing dynamics of magnetic (anti-)skyrmions within the Hamiltonian formalism
B. F. McKeever, D. R. Rodrigues, D. Pinna +3
We derive an effective Hamiltonian system describing the low energy dynamics of circular magnetic skyrmions and antiskyrmions. Using scaling and symmetry arguments we model (anti-)…
Effective description of domain wall strings
Davi R. Rodrigues, Ar. Abanov, J. Sinova +1
The analysis of domain wall dynamics is often simplified to one dimensional physics. For domain walls in thin films, more realistic approaches require the description as two dimens…

Davi R. Rodrigues, Karin Everschor-Sitte, Oleg A. Tretiakov +2
We propose a Hamiltonian dynamics formalism for the current and magnetic field driven dynamics of ferromagnetic and antiferromagnetic domain walls in one dimensional systems. To de…
