Vortex core magnetization dynamics induced by thermal excitation
Tiago S. Machado, Tatiana G. Rappoport, Luiz C. Sampaio
We investigate the effect of temperature on the dynamic properties of magnetic vortices in small disks. Our calculations use a stochastic version of the Landau-Lifshitz-Gilbert (LL…
From local to critical fluctuations in lattice models: a non-perturbative renormalization-group approach
T. Machado, N. Dupuis
We propose a modification of the non-perturbative renormalization-group (NPRG) which applies to lattice models. Contrary to the usual NPRG approach where the initial condition of t…
Magnetoresistance in nanostructures: the role of nonuniform current
Tiago S. Machado, M. Argollo de Menezes, Tatiana G. Rappoport +1
We developed a method to calculate the magnetoresistance of magnetic nanostructures. We discretize a magnetic disk in small cells and numerically solve the Landau-Lifshitz-Gilbert…
Static and dynamic properties of vortices in anisotropic magnetic disks
Tiago S. Machado, Tatiana G. Rappoport, Luiz C. Sampaio
We investigate the effect of the magnetic anisotropy () on the static and dynamic properties of magnetic vortices in small disks. Our micromagnetic calculations reveal that fo…
