Strain-controlled magnetism and magnetoelasticity in monolayer NiPS and CrPS
Balázs Nagyfalusi, Alvaro Bermejillo-Seco, Linde de Jong +5
We develop a first-principles framework for magnetoelastic coupling in two-dimensional magnets based on a strain-dependent Heisenberg model. In this approach, strain derivatives of…
Magnetic ground states of CrPS and NiPS monolayers from long-range exchange interactions
Balazs Nagyfalusi, Ritesh Das, Alvaro Bermejillo-Seco +4
We investigate the magnetic properties of monolayer CrPS and NiPS by combining first-principles calculations, second-principles spin models, and Monte Carlo simulations. Un…
Magnon-polaron mediated spin Seebeck effect in altermagnets
Ilia Moghayer, Ritesh Das, Yaroslav M. Blanter
Altermagnets, distinguished by compensated antiparallel spins yet nondegenerate magnon spectra, bridge the gap between ferromagnets and antiferromagnets. Although several probes su…
Magnomechanical Coupling in Suspended 2D van der Waals Ferromagnets
Ritesh Das, Alvaro Bermejillo-Seco, Herre S. J. van der Zant +2
Magnomechanical systems provide a promising route for exploring coherent hybrid magnon-phonon interactions and hybrid information processing, but their realization has so far been…
Dipolar-exchange spin waves in thin bilayers
Rob den Teuling, Ritesh Das, Artem V. Bondarenko +3
We investigate the dipolar-exchange spin wave spectrum in thin ferromagnetic bilayers with inplane magnetization, incorporating interlayer exchange coupling and intra- and interlay…
Spin Wave Dispersion of the van der Waals Antiferromagnet NiPS
Ritesh Das, Rob den Teuling, Artem V. Bondarenko +4
We calculate the magnon dispersion spectra of the two-dimensional zigzag van der Waals antiferromagnet NiPS for monolayer, bilayer, and bulk systems as a function of an externa…
