Claim Text:
1. A magnetic tunnel junction comprising: a conductive first magnetic electrode comprising a magnetic recording material; a conductive second magnetic electrode spaced from the first electrode and comprising a magnetic reference material; a non-magnetic tunnel insulator material comprising MgO between the first and second electrodes, the tunnel insulator material being devoid of B; and the magnetic recording material or the magnetic reference material of at least one of the first and second electrodes comprising a crystalline magnetic region that comprises Co and Fe and that is devoid of B, the at least one of the first and second electrodes comprising a non-magnetic MgO-comprising region and an amorphous metal region, the amorphous metal region comprising an alloy of a) at least one of Zr, W, Mo, and Cr, and at least one of Fe, Co, and Ni, or b) Al and Ni, the Co and Fe-comprising crystalline magnetic region that is devoid of B being between the tunnel insulator material and the MgO-comprising region, the amorphous metal region being between the MgO-comprising region and the Co and Fe-comprising crystalline magnetic region that is devoid of B.
