Summary edit
| Description |
English: Spin Polarized Tunneling (Giant Magnetoresistance)
It is the effect produced by an external magnetic field in the behavior of an electric current with a potential barrier. The potential prevents the crossing of the electrons, so that the material shows a great (almost infinite) resistivity. If we introduce an external magnetic field,orthogonal to the direction of the current, the conduction electrons become transversally polarized and, therefore, they cross the barrier by the tunneling effect, which does not work if the electrons are unpolarized. The resistivity is highly decreased by polarizing the electrons. The resistivity is changed by an external magnetic field. Based on the theory of Spin by Martin Rivas.

Es el efecto producido por un campo magnético externo en el comportamiento de una corriente eléctrica frente a una barrera de potencial. La barrera de potencial impide el cruce de los electrones, de forma que el material presenta una resistencia inmensa (casi infinita). Si introducimos un campo magnético externo ortogonal a la dirección de la corriente, los electrones de conducción pasan a estar polarizados transversalmente y por tanto pueden cruzar la barrera de potencial por efecto tunel. Lo que no sería posible si no están polarizados. La resistividad disminuye enormemente al polarizar los electrones. Estos materiales se llaman Su resistencia se puede cambiar por un campo magnético externo. Basado en la teoría del Spin por Martin Rivas. Más información en www.SpinningParticles.com |
