Local magnetic resonance of scalar spin chirality
Mar Ferri-Cortés, Joaquin Fernández-Rossier
Quantum states with finite scalar spin chirality carry an orbital magnetic moment that has eluded direct measurement. We show that a local drive breaks the cyclic symmetry and acti…
Remote spin control in Haldane spin chains
Y. del Castillo, A. Ferrón, J. Fernández-Rossier
We consider the remote manipulation of the quantum state of the edge fractional spins of Haldane spin chains using a weak local perturbation on the other edge. We derive an effecti…
Giant spatial anisotropy of magnon lifetime in altermagnets
A. T. Costa, J. C. G. Henriques, J. Fernández-Rossier
Altermagnets are a new class of magnetic materials with zero net magnetization (like antiferromagnets) but spin-split electronic bands (like ferromagnets) over a fraction of recipr…
Magnetic single wall CrI3 nanotubes encapsulated within multiwall Carbon Nanotubes
Ihsan Caha, Loukya Boddapatti, Aqrab ul Ahmad +8
CrI3 is a layered ferromagnetic insulator that has recently attracted enormous interest as it was the first example of a stand-alone monolayer ferromagnet, paving the way towards t…
Beyond spin models in orbitally-degenerate open-shell nanographenes
J. C. G. Henriques, D. Jacob, A. Molina-Sánchez +3
The study of open-shell nanographenes has relied on a paradigm where spins are the only low-energy degrees of freedom. Here we show that some nanographenes can host low-energy exci…
Designer spin models in tunable two-dimensional nanographene lattices
J. C. G. Henriques, Mar Ferri-Cortés, J. Fernández-Rossier
Motivated by recent experimental breakthroughs, we propose a strategy to design two-dimensional spin lattices with competing interactions that lead to non-trivial emergent quantum…
Theory of triangulene two-dimensional crystals
R. Ortiz, G. Catarina, J. Fernández-Rossier
Equilateral triangle-shaped graphene nanoislands with a lateral dimension of benzene rings are known as triangulenes. Individual triangulenes are open-shell molecules…
Topological spin waves in the atomic-scale magnetic skyrmion crystal
A. Roldán-Molina, A. S. Nunez, J. Fernández-Rossier
We study the spin waves of the triangular skyrmion crystal that emerges in a two dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalons…
