Fast vortex wall motion in wide Permalloy strips from double switching of the vortex core
Virginia Estévez, Lasse Laurson
We study vortex domain wall dynamics in wide Permalloy strips driven by applied magnetic fields and spin-polarized electric currents. As recently reported [V. Estévez and L. Laurso…
Magnetic domain-wall dynamics in wide permalloy strips
Virginia Estevez, Lasse Laurson
Domain walls in soft permalloy strips may exhibit various equilibrium micromagnetic structures depending on the width and thickness of the strip, ranging from the well-known transv…
Head-to-Head Domain Wall Structures in Wide Permalloy Strips
Virginia Estevez, Lasse Laurson
We analyze the equilibrium micromagnetic domain wall structures encountered in Permalloy strips of a wide range of thicknesses and widths, with strip widths up to several micromete…
Robustness of the magnetoresistance of nanoparticle arrays
V. Estevez, E. Bascones
Recent work has found that the interplay between spin accumulation and Coulomb blockade in nanoparticle arrays results in peaky I-V and tunneling magnetoresistance (TMR) curves and…
Absence of scaling in transport through two-dimensional nanoparticle arrays
V. Estevez, E. Bascones
We analyze the transport in disordered two-dimensional nanoparticle arrays. We show that the commonly used scaling hypothesis to fit the I-V curves does not describe the electronic…
Huge enhancement of the magnetoresistance in nanoparticle arrays
V. Estevez, E. Bascones
We show that the interplay between charging effects and the non-equilibrium spin accumulation has a dramatic effect in the current through an array of nanostructures attached to fe…
