Magnetic exchange interactions in monolayer CrI from many-body wavefunction calculations
Michele Pizzochero, Ravi Yadav, Oleg V. Yazyev
The marked interplay between the crystalline, electronic, and magnetic structure of atomically thin magnets has been regarded as the key feature for designing next-generation magne…
Spin-reversal energy barriers of 305 K for Fe ions with linear ligand coordination
Lei Xu, Ziba Zangeneh, Ravi Yadav +4
A remarkably large magnetic anisotropy energy of 305 K is computed by quantum chemistry methods for divalent Fe substitutes at Li-ion sites with point-group s…
Highly dispersive magnons with spin-gap like features in the frustrated ferromagnetic S=1/2 chain compound Ca2Y2Cu5O10 detected by inelastic neutron scattering
M. Matsuda, J. Ma, V. O. Garlea +10
We report inelastic neutron scattering experiments in Ca2Y2Cu5O10 and map out the full one magnon dispersion which extends up to a record value of 53 meV for frustrated ferromagnet…
Large off diagonal exchange couplings and spin liquid states in symmetric iridates
Ravi Yadav, Satoshi Nishimoto, Manuel Richter +2
Iridate oxides on a honeycomb lattice are considered promising candidates for realization of quantum spin liquid states. We investigate the magnetic couplings in a structural model…
Superexchange interactions between spin-orbit-coupled ions in oxides with face-sharing ligand octahedra
Lei Xu, Ravi Yadav, Viktor Yushankhai +3
Using ab initio wave-function-based calculations, we provide valuable insights with regard to the magnetic exchange in 5 and 4 oxides with face-sharing ligand octahedra, BaIr…
