Quantum coherence driven magnetic ordering in biased three level coordination compounds
Jhoan Alexis Fernandez Sanchez, Luis Alejandro Sierra Ossa, Henning Hammar +2
Novel understanding of the recent nanomagnet tailoring experiments and the possibility to further unveil the mechanisms by which the magnetic interactions arise in an atom by atom…
Spin-dependent heat signatures of single-molecule spin dynamics
Henning Hammar, Juan-David Vasquez Jaramillo, Jonas Fransson
We investigate transient spin-dependent thermoelectric signatures in a single-molecule magnet under the effect of a time-dependent voltage pulse. We model the system using nonequil…
Dynamical exchange and phase induced switching of a localized molecular spin
Henning Hammar, Jonas Fransson
The dynamics of a localized molecular spin under the influence of external voltage pulses is addressed using a generalized spin equation of motion. The approach incorporates anisot…
Electronically Mediated Magnetic Anisotropy in Vibrating Magnetic Molecules
J. D. Vasquez Jaramillo, H. Hammar, J. Fransson
We address the electronically induced anisotropy field acting on a spin moment comprised in a vibrating magnetic molecule located in the junction between ferromagnetic metals. Unde…
Transient spin dynamics in a single-molecule magnet
Henning Hammar, Jonas Fransson
We explore the limitations and validity of semi-classically formulated spin equations of motion. Using a single-molecule magnet as a test model, we employ three qualitatively diffe…
Voltage induced switching dynamics of a coupled spin pair in a molecular junction
T. Saygun, J. Bylin, H. Hammar +1
Molecular spintronics is made possible by the coupling between electronic configuration and magnetic po- larization of the molecules. For control and application of the individual…
Time-dependent spin and transport properties of a single-molecule magnet in a tunnel junction
H. Hammar, J. Fransson
In single-molecule magnets, the exchange between a localized spin moment and the electronic background provides a suitable laboratory for studies of dynamical aspects of both local…
Molecular Graphene under the Eye of Scattering Theory
H. Hammar, P. Berggren, J. Fransson
The recent experimental observations of designer Dirac Fermions and topological phases in molecular graphene are addressed theoretically. Using scattering theory we calculate the e…
