Moving Analogue Horizons in Stationary Ferroelectrics
David Galvez-Poblete, Rubén M. Otxoa, Alvaro S. Nunez +1
We show that a traveling modulation of the polarization-gradient stiffness in a ferroelectric material induces an effective flow in its collective polarization dynamics. Within a c…
Spin-orbit torque-driven synthetic antiferromagnetic oscillator
P. K. Rout, J. Godinho, F. Vilsmeier +9
Antiferromagnets offer a promising route toward robust spintronic devices because of their compensated magnetic order and exchange-enhanced spin dynamics. Here, we demonstrate a sp…
Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot
Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27
Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…
Exact Solution for Current-Driven Domain-Wall Dynamics Beyond Lorentz Contraction in Antiferromagnets with Dzyaloshinskii-Moriya Interaction
Mu-Kun Lee, Rubén M. Otxoa, Masahito Mochizuki
We study current-driven domain-wall (DW) dynamics in antiferromagnets (AFMs) with Dzyaloshinskii-Moriya interaction (DMI). We obtain an exact analytical solution for spiral DW dyna…
Sub-GHz Breathing Dynamics of Magnetic Hopfions
Felipe Tejo, Rubén M. Otxoa
Magnetic hopfions are three-dimensional topological solitons whose static stability has recently been confirmed in experiments, yet their dynamical modes remain largely unexplored.…
Skyrmion Hall effect and shape deformation of current-driven bilayer skyrmions in synthetic antiferromagnets
Mu-Kun Lee, Javier A. Vélez, Rubén M. Otxoa +1
The commonly believed absence of skyrmion Hall effect for topologically trivial magnetic skyrmions is reconsidered for bilayer skyrmions in synthetic antiferromagnets driven by spi…
