This originates from their strong hybridization with the ni and fe atoms of the permalloy (py) electrode the spin-valve effect is observed up to 240 k,. Spin valve transistor is different from conventional transistor in this for conduction we use spin polarization of electrons only electrons with correct spin. Transistor based on such films [3] spin valve devices are fabricated by defining ferromagnetic nife electrodes with a lift off technique.

A spin valve multilayer serves as a base region of an n silicon metal base transistor structure metal base transistors have been proposed for. This design is called a bottom spin valve - the biased layer is now at the bottom this presents some growth problems as the biasing femn layer does not grow on top of a magnetically saturated film - so its magnetic structure is random.
