Temperature dependence of spin-model parameters in ferrimagnets
Marta Yanguas, José M. Lendínez, Theodor Griepe +3
We compute the temperature dependence of effective spin-model parameters in two-sublattice ferrimagnets with antiparallel and inequivalent sublattice magnetizations using Green's-f…
A spin-bond theory unifying non-relativistic spin splitting and emergent spin-orbit textures
S. Allende, R. M. Otxoa
Magnetic order with vanishing net magnetization can produce non-relativistic spin-split bands, broadly categorized into even-parity altermagnets and odd-parity \(p\)-wave magnets.…
Universal theory of domain-wall width in multi-sublattice Heisenberg magnets
José M. Lendínez, Marta Yanguas, Theodor Griepe +4
We propose a universal expression for the domain-wall width in generic multi-sublattice Heisenberg magnets, applicable to ferro-, antiferro-, and ferrimagnetic orders. The result f…
Chaotic Proliferation of Relativistic Domain Walls for Reservoir Computing
J. A. Vélez, M. -K. Lee, G. Tatara +8
Magnetic domain walls in antiferromagnets have been proposed as key components for faster conventional information processing, thanks to their enhanced stability and ultrafast prop…
Antiferromagnetic Switching in MnAu Using a Novel Laser Induced Optical Torque on Ultrafast Timescales
J. L. Ross, P-I. Gavriloaea, F. Freimuth +6
Efficient manipulation of the Néel vector in antiferromagnets can be induced by generation of spin orbit (SOT) or spin-transfer (STT) torques. Here we predict another possibility f…
Lattice structure dependence of laser-induced ultrafast magnetization switching in ferrimagnets
J. A. Vélez, R. M. Otxoa, U. Atxitia
The experimental discovery of single-pulse ultrafast magnetization switching in ferrimagnetic alloys, such as GdFeCo and MnRuGa, opened the door to a promising route toward faster…
Generalised form of the magnetic anisotropy field in micromagnetic and atomistic spin models
Jack B. Collings, Ricardo Rama-Eiroa, Rubén M. Otxoa +2
We present a general approach to the derivation of the effective anisotropy field which determines the dynamical behaviour of magnetic spins according to the Landau-Lifshitz-Gilber…
Inertial domain wall characterization in layered multisublattice antiferromagnets
R. Rama-Eiroa, P. E. Roy, J. M. González +3
The motion of a Néel-like domain wall induced by a time-dependent staggered spin-orbit field in the layered collinear antiferromagnet MnAu is explored. Through…
Topological energy release from collision of relativistic antiferromagnetic solitons
R. M. Otxoa, R. Rama-Eiroa, P. E. Roy +3
Magnetic solitons offer functionalities as information carriers in multiple spintronic and magnonic applications. However, their potential for nanoscale energy transport has not be…
Steady one-dimensional domain wall motion in biaxial ferromagnets: mapping of the Landau-Lifshitz equation to the sine-Gordon equation
Ricardo Rama-Eiroa, Rubén M. Otxoa, Pierre E. Roy +1
Motivated by the difference between the dynamics of magnetization textures in ferromagnets and antiferromagnets, the Landau-Lifshitz equation of motion is explored. A typical one-d…
Electrically induced and detected Néel vector reversal in a collinear antiferromagnet
J. Godinho, H. Reichlova, D. Kriegner +11
Electrical detection of the 180 deg spin reversal, which is the basis of the operation of ferromagnetic memories, is among the outstanding challenges in the research of antiferroma…
Dynamical influence of vortex-antivortex pairs in magnetic vortex oscillators
Rubén M. Otxoa, Sébastien Petit-Watelot, Mauricio Manfrini +3
We study the magnetization dynamics in a nanocontact magnetic vortex oscillators as function of temperature. Low temperature experiments reveal that the dynamics at low and high cu…
