Claim:
1. A magnetic device, comprising: a magnetic tunnel junction having a magnetic reference layer and a magnetic free layer, the magnetic reference layer and the magnetic free layer separated by a non-magnetic tunneling barrier layer, the magnetic reference layer having a magnetic vector having a fixed magnetic direction, the magnetic free layer having a magnetic vector with a variable magnetic direction; a magnetic polarizer layer having magnetic vector with a direction that is perpendicular to the magnetic direction of the magnetic reference layer and the magnetic free layer, wherein the magnetic polarizer aligns polarity of electrons of electric current passing therethrough in the magnetic direction of the magnetic polarizer, thereby creating a spin current; and a spin current injection capping layer disposed between the magnetic tunnel junction and the magnetic polarizer, the spin current injection capping layer comprising a non-magnetic insulator on the magnetic free layer and a magnetic conductor on the non-magnetic insulator, the spin current injection capping layer injecting spin polarized current into the magnetic tunnel junction through tunneling.
