Geometrical Confinement of Magnetic Domains and Domain Walls on Two-Dimensional Cylindrical-Shaped Ferromagnetic Surfaces
Gabriel Martínez-Carracedo, Aurelio Hierro-Rodríguez, Amador García-Fuente +1
The rolling of two-dimensional (2D) van der Waals (vdW) magnetic monolayers into cylindrical architectures provides an ideal platform for confining magnetic domain walls (DWs) with…
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…
Low-energy model for doped graphene nanoribbons
J. Ferrer, A. García-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 Sípos, Amador García-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 Martínez-Carracedo, Amador García-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…
Surface reconstruction limited magnetism of the nodal loop semimetal CaP
Assem Alassaf, János Koltai, Amador García-Fuente +1
Nodal loop semimetals are topological materials with drumhead surface states characterized by reduced kinetic energy. If the Fermi energy of such a system is near these nondispersi…
Tuning magnetic exchange interactions in 2D magnets: the case of CrGeX (X = Se, Te) and Janus CrGe(Se,Te) monolayers
Gabriel Martínez-Carracedo, Amador García-Fuente, László Oroszlány +2
We present a computational study to explore the potential of different experimental approaches to tune the magnetic interactions in two-dimensional van der Waals magnets. We select…
Solution of the mean-field Hubbard model of graphene rectangulenes
Amador García-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…
Relativistic magnetic interactions from non-orthogonal basis sets
Gabriel Martínez-Carracedo, László Oroszlány, Amador García-Fuente +4
We propose a method to determine the magnetic exchange interaction and on-site anisotropy tensors of extended Heisenberg spin models from density functional theory including relati…
Full analytical solution of finite-length armchair/zigzag nanoribbons
A. García-Fuente, D. Carrascal, G. Ross +1
Finite-length armchair graphene nanoribbons can behave as one dimensional topological materials, that may show edge states in their zigzag-terminated edges, depending on their widt…
Relevance of Shockley states on the electrical and thermoelectric response of gold-based single-molecule junctions
Saúl Sánchez-González, Amador García-Fuente, Jaime Ferrer
Noble metals break preferably exposing (111)-oriented surfaces, that host Shockley type surface states (SSs). Nevertheless, the relevance of SSs on the electrical properties of gol…
Electrically driven singlet-triplet transition in triangulene spin-1 chains
Gabriel Martínez-Carracedo, László Oroszlány, Amador García-Fuente +2
Recently, graphene triangulene chains have been synthesized and their magnetic response has been analyzed by STM methods by Mishra and coworkers (Nature 598, 287 (2021)). Motivated…
