The current induced magnetization reversal in nanoscale spin valves is a potential alternative to magnetic field switching in magnetic memories. We show that the critical switching current can be decreased by an order of magnitude by strategically distributing the resistances in the magnetically active region of the spin valve. In addition, we simulate full switching curves and predict a new precessional state.

    A junction between two ferromagnetic metal layers with fixed spins in one of them and free spins in the other (spin valve) is considered. The junction is placed in an external magnetic field that orients the free layer oppositely to the fixed layer. It is shown that the spin-polarized electron...

    The CoFe2/CoFe2O4 system has been considered for use as hard electrodes in spin valve devices. In this letter, we focus on the nature and intensity of the magnetic exchange coupling between the two phases. CoFe2/CoFe2O4 and CoFe2O4/CoFe2 bilayers were fabricated by pulsed laser deposition from a...

    We report on field annealing effects in spin valves with an IrMn pinning layer and spin valves with a synthetic antiferromagnet. The exchange bias field and magnetoresistance of spin valves with an IrMn/CoFe bilayer at the bottom improve drastically upon annealing in large magnetic fields. The...
