The constant search for the miniaturization of electronic components has been one of the biggest challenges for application in new processors and logic devices. However, the spintronics proposal, in which the electron's spin is essential rather than the charge, demonstrates remarkable effectiveness with low energy consumption and stability. This makes spintronics one of the main promises …
Skyrmions are quasi-particles proposed theoretically by the English physicist Tony Skyrme in 1960 for stabilizing hadrons as quantized topological defects. The idea of ¿¿the skyrmion as a magnetic texture was proposed in theoretical form in 1989, and confirmed experimentally only in 2009 in MnSi. Some of the most interesting characteristics of skyrmions are their nanometric size, topologi…
In this work we will study the dynamical behavior of skyrmions on the presence of different defects configurations.Proposed initially by the english physicist Tony Skyrme, skyrmions are quasi-particles corresponding to a spin distribution pointing in all directions wrapping a sphere. It formation is primordially by two concurrent interactions: the ferromagnetic exchange and the Dzyaloshin…
In this work, we will study the dynamic behavior of skyrmions on chiral magnets, in the presence of periodic pinning potentials. In particular, we will analyze pinning centers with funnel-type geometry. Initially proposed by the English physicist Tony Skyrme, skyrmions are quasi-particles that correspond to a distribution of spins pointing in all directions under a sphere and are present …
Skyrmions are quasi-particles that were originally proposed theoretically by the British physicist Tony Skyrme. Magnetic skyrmions correspond to a distribution of spins pointing in all directions under a sphere, and are present in ferromagnetic materials, liquid crystals, Bose-Einstein condensates and others. Recently, magnetic skyrmions were observed in chiral magnets. In these materials…
In the present work we propose the study of critical currents and dynamical behavior of vortices in type II Superconducting stripes with Kagomé and hexagonal arrays of pinning centers. In addition to the finite geometry and pinning effects, the system behavior when external parameters such as temperature and magnetic field are changed will be analyzed. When the transport current J exceeds…

Skyrmions are magnetic quasiparticles characterized by a topological charge. The magnetic moments composing skyrmion wrapper a the unit sphere, pointing in all directions. The skyrmion motion can be achieved by thermal gradient, magnetic field gradients, spin waves and applied spin polarized current. The applied current density needed to depin skyrmions is between 4 and 5 magnitude orders…
Magnetic skyrmions corresponds to a spin distribution pointing in all directions around a sphere, and they are present in ferromagnetic materials, liquid crystals, Bose-Einstein condensates and others. Recently, magnetic skyrmions were also observed in chiral magnets. In these materials, skyrmions form a vortex-like structure and organize themselves in a regular triangular lattice due to …
