摘要
We study charge transport in a two dimensional hybrid systems consisting of nonmagnetic two dimensional electron gas with spin-orbit interaction sandwiched between a Ferromagnetic lead and a normal metallic lead (FM/2DEG/NM). An {\it absolute spin valve effect} is shown to exist. It is shown that the conductance of such a hybrid system changes upon rotating the magnetization such that it always stays perpendicular to the current direction. An ASVC ({\it Absolute Spin Valve Coefficient}) is defined to quantify this effect and its dependence on various parameter is studied.
