Abstract

It will be shown that the well known technique of Magnetic Focussing can be used to probe the spin configuration in a one dimensional electron channel. Spin polarization occurs which can be controlled by geometry, the relation to the 0.7 structure will be discussed. When the confinement is relaxed a single line of electrons will relax into two or more rows and here it will be shown that this can be detected and spin texture explored.
