Abstract:
1. A magnetic junction comprising: a free layer having a first magnetic moment switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction; a symmetry filter that transmits charge carriers having a first symmetry with a higher probability than the charge carriers having a second symmetry; a pinned layer having a second magnetic moment pinned in a particular direction, the symmetry filter residing between the free layer and the pinned layer; wherein at least one of the free layer and the pinned layer has the charge carriers of the first symmetry at a Fermi level in a spin channel, lacks the charge carriers of the first symmetry at the Fermi level in another spin channel, lies substantially in a plane and has a nonzero magnetic moment component substantially perpendicular to the plane, the symmetry filter and at least one of the free layer and the pinned layer having a lattice mismatch of less than seven percent.
