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 …
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…

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 …
