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…
Coexistence of Antiferromagnetism and Superconductivity in Mn/Nb(110)
Roberto Lo Conte, Maciej Bazarnik, Krisztián Palotás +5
We report on the structural and magnetic properties of single and double atomic layers of Mn on a clean and unreconstructed Nb(110) substrate. Low-temperature scanning tunneling sp…
Electronic and Magnetic Properties of Building Blocks of Mn and Fe Atomic Chains on Nb(110)
András Lászlóffy, Krisztián Palotás, Levente Rózsa +1
We present results for the electronic and magnetic structure of Mn and Fe clusters on Nb(110) surface, focusing on building blocks of atomic chains as possible realizations of topo…
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…
