Controlled motion of skyrmions in a magnetic antidot lattice
J. Feilhauer, S. Saha, J. Tobik +3
Future spintronic devices based on skyrmions will require precise control of the skyrmion motion. We show that this goal can be achieved through the use of magnetic antidot arrays.…
Free-energy landscapes in magnetic systems from metadynamics
Jaroslav Tobik, Roman Martonak, Vladimir Cambel
Knowledge of free energy barriers separating different states is critically important for assessment of long-term stability of information stored in magnetic devices. This informat…
Dynamics of Vortex Nucleation in Nanomagnets with Broken Symmetry
Jaroslav Tobik, Vladimir Cambel, Goran Karapetrov
We investigate fundamental processes that govern dynamics of vortex nucleation in sub-100 nm mesoscopic magnets. We focus on a structure with broken symmetry - Pacman-like nanomagn…
Raman Tensor Calculation for Magnesium Phthalocyanine
Jaroslav Tobik, Erio Tosatti
We present ab-initio density functional (DFT) calculations of the vibrational spectra of neutral Magnesium phthalocyanine (MgPc) molecule and of its Raman scattering intensities.
Strong Correlations in Electron Doped Phthalocyanine Conductors Near Half Filling
Erio Tosatti, Michele Fabrizio, Jaroslav Tobik +1
We propose that electron doped nontransition metal-phthalocyanines (MPc) like ZnPc and MgPc, similar to those very recently reported, should constitute novel strongly correlated me…
Electric fields with ultrasoft pseudo-potentials: applications to benzene and anthracene
Jaroslav Tobik, Andrea Dal Corso
We present density functional perturbation theory for electric field perturbations and ultra-soft pseudopotentials. Applications to benzene and anthracene molecules and surfaces ar…
