Three-Dimensional Shankar Skyrmions in Frustrated Antiferromagnets
Vladyslav M. Kuchkin, Ricardo Rama-Eiroa, Carlos Saji +2
We formulate a continuum theory for three-dimensional (3D) Shankar skyrmions in frustrated chiral antiferromagnets (AFs) and derive the conditions for metastable finite-size $π_3(S…
Configurable antiferromagnetic domains and lateral exchange bias in atomically thin CrPS4
Yu-Xuan Wang, Thomas K. M. Graham, Ricardo Rama-Eiroa +12
Interfacial exchange coupling between antiferromagnets (AFMs) and ferromagnets (FMs) crucially makes it possible to shift the FM hysteresis, known as exchange bias, and to switch A…
Field-induced antiferromagnetic correlations in a nanopatterned van der Waals ferromagnet: a potential artificial spin ice
Avia Noah, Nofar Fridman, Yishay Zur +15
Nano-patterned magnetic materials have opened new venues on the investigation of strongly correlated phenomena including artificial spin-ice systems, geometric frustration, magneti…
Nanoscale magnetism and magnetic phase transitions in atomically thin CrSBr
Märta A. Tschudin, David A. Broadway, Patrick Reiser +13
Since their first observation in 2017, atomically thin van der Waals (vdW) magnets have attracted significant fundamental, and application-driven attention. However, their low orde…
Magnetic imaging and domain nucleation in CrSBr down to the 2D limit
Yishay Zur, Avia Noah, Carla Boix-Constant +7
Recent advancements in 2D materials have revealed the potential of van der Waals magnets, and specifically of their magnetic anisotropy that allows applications down to the 2D limi…
Multistep magnetization switching in orthogonally twisted ferromagnetic monolayers
Carla Boix-Constant, Sarah Jenkins, Ricardo Rama-Eiroa +3
The advent of twist-engineering in two-dimensional (2D) crystals enables the design of van der Waals (vdW) heterostructures exhibiting emergent properties. In the case of magnets,…
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…
Temperature-dependent critical spin-orbit field for orthogonal switching in antiferromagnets
R. Rama-Eiroa, R. M. Otxoa, U. Atxitia
The discovery of current-induced spin-orbit torque (SOT) orthogonal reorientation, also known as orthogonal switching, of metallic MnAu and CuMnAs has opened the door for ultra…
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…
Walker-like Domain Wall breakdown in layered Antiferromagnets driven by staggered spin-orbit fields
Rubén M. Otxoa, P. E. Roy, R. Rama-Eiroa +2
Within linear continuum theory, no magnetic texture can propagate faster than the maximum group velocity of its spin waves. Here we report a transient regime due to the appearance…
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…
