[EN] The work you are about to read humbly pushes ahead the wheel of modern natural sciences by propelling it particular wheelarm called electromagnetism. Moreover, it adds a modest contribution to building the bridge to
future application of spintronic devices. Spintronics (a neologism meaning
spin transport electronics) is an emerging technology combining two
twin fields of physics: electronics and magnetism. The first one is based on
the existence of electric charge and the second on it magnetic property: spin.
Spintronics takes, therefore, twofold advantage of the electron.
[ES] Este trabajo se va a
centrar en un area de la física moderna denominada espintrónica (neologismo
del inglés Spintronics). Esta novedosa tecnología combina dos campos
de física: electrónica y magnetismo. La existencia del electrón como unidad
de carga y por otra parte la propiedad magnética de dicha unidad, el spin,
forman la idea y la base de la espintrónica.
