Chemical potential of magnetic skyrmion quasiparticles in heavy metal/iron bilayers
Balázs Nagyfalusi, László Udvardi, László Szunyogh +1
We performed metadynamics Monte Carlo simulations to obtain the free energy as a function of the topological charge in the skyrmion-hosting magnetic model systems (PtIr$_{…
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…
Spin reorientation transition in an ultrathin Fe film on W(110) induced by Dzyaloshinsky-Moriya interactions
Balázs Nagyfalusi, László Udvardi, László Szunyogh +1
Controlling the preferred direction of the magnetic moments is essential for the design of spintronic devices based on ultrathin films and heterostructures. As the film thickness o…
Metadynamics study of the temperature dependence of magnetic anisotropy and spin-reorientation transitions in ultrathin films
Balázs Nagyfalusi, László Udvardi, László Szunyogh
We employ metadynamics simulations to calculate the free energy landscape of thin ferromagnetic films and perform a systematic study of the temperature dependence of magnetic aniso…
Magnetic structure of monatomic Fe chains on Re(0001): emergence of chiral multi-spin interactions
András Lászlóffy, Levente Rózsa, Krisztián Palotás +2
We present results of first-principles calculations of the magnetic properties of Fe chains deposited on the Re(0001) surface. By increasing the length of the chain, a transition i…
Exchange interactions from a nonorthogonal basis set: from bulk ferromagnets to the magnetism in low-dimensional graphene systems
László Oroszlány, Jaime Ferrer, András Deák +2
We present a computational method to determine the exchange constants in isotropic spin models. The method uses the Hamiltonian and overlap matrices computed from density functiona…
