Landau-Lifshitz-Bloch simulations of the magnetocaloric effect in continuous ferromagnetic-paramagnetic transitions
Luis M. Moreno-Ramírez, Luis Sánchez-Tejerina, Óscar Alejos +2
The usefulness of modeling magnetocaloric materials expands from the understanding of their behavior to the prediction of new materials, playing a fundamental role in the optimizat…
Analytical dispersion relation for forward volume spin waves in ferrimagnets near the angular momentum compensation condition
Luis Sánchez-Tejerina, David Osuna Ruiz, Víctor Raposo +3
Antiferromagnetic magnonics has become the focus of intense scientific research because of the advantages of these materials compared to ferromagnets. However, ferrimagnetic materi…
Current-Driven Domain Wall Motion in Curved Ferrimagnetic Strips Above and Below the Angular Momentum Compensation
David Osuna Ruiz, Óscar Alejos, Víctor Raposo +1
Current driven domain wall motion in curved Heavy Metal/Ferrimagnetic/Oxide multilayer strips is investigated using systematic micromagnetic simulations which account for spin-orbi…
Spin Waves in Ferrimagnets near the Angular Magnetization Compensation Temperature: A Micromagnetic Study
Luis Sánchez-Tejerina, David Osuna Ruiz, Eduardo Martínez +2
Spin wave propagation along a ferrimagnetic strip with out-of-plane magnetization is studied by means of micromagnetic simulations. The ferrimagnetic material is considered as form…
A review of the classical Doppler effect based on the mathematical description of the phase function
Óscar Alejos, José Mar\'\ia Muñoz
The classical Doppler effect is explicitly reformulated by determining the phase function associated with a moving source. General expressions for frequency shift and aberration ar…
Novel interpretation of recent experiments on the dynamics of domain walls along ferrimagnetic strips
Eduardo Martínez, Víctor Raposo, Óscar Alejos
Domain wall motion along ferrimagnets is evaluated using micromagnetic simulations and a collective-coordinates model, both considering two sublattices with independent parameters.…
Domain Wall Motion in Magnetic Nanostrips
Oscar Alejos, Víctor Raposo, Eduardo Martínez
Domain walls are the transition regions between two magnetic domains. These objects have been very relevant during the last decade, not only due to their intrinsic interest in the…

Ultrathin ferromagnetic strips with high perpendicular anisotropy have been proposed for the development of memory devices where the information is coded in tiny domains separated…
Spin-orbit torques for current parallel and perpendicular to a domain wall
Tomek Schulz, Oscar Alejos, Eduardo Martinez +10
We report field- and current-induced domain wall (DW) depinning experiments in Ta/Co20Fe60B20/MgO nanowires through a Hall cross geometry. While purely field-induced depinning show…
