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…
Low-energy model for doped graphene nanoribbons
J. Ferrer, A. GarcÃa-Fuente, Y. Yang +2
We analyse in this article the many-body behavior of free-standing doped graphene nanoribbons where the chemical potential lies inside the bulk single-particle bands. We perform an…
Proximity-Induced Spin Reorientation in Monolayer CrI on Hexagonal WTe
Dániel Tibor Pozsár, Marcell Balázs SÃpos, Amador GarcÃa-Fuente +7
Magnetic anisotropy controls the orientation and thermal stability of two-dimensional magnetic order. Predicting proximity-induced changes in anisotropy requires linking the electr…
Strain induced magnetic phase transitions in Fe3GeTe2 monolayer
Anjali Jyothi Bhasu, Satish Kumar, Mátyás Török +11
We investigate the magnetic properties of a monolayer of Fe3GeTe2 as a function of the lattice constant by combining first-principles calculations with atomistic spin dynamics simu…
Graphene-based quantum heterospin graphs
Gabriel MartÃnez-Carracedo, Amador GarcÃa-Fuente, László Oroszlány +2
We investigate from first principles a variety of low-dimensional open quantum spin systems based on magnetic nanographene structures that contain spin-1/2 and spin-1 triangulenes…
Solution of the mean-field Hubbard model of graphene rectangulenes
Amador GarcÃa-Fuente, Jaime Ferrer
We present a complete analytical solution of the mean-field Hubbard model of undoped and doped graphene rectangulenes. These are non-chiral ribbons of arbitrary length and width, w…
