Abstract
In one general embodiment, an apparatus includes a magnetic tunnel junction device having a reference layer, a free layer, and a tunnel barrier layer between the free and reference layers. The tunnel barrier layer is primarily crystalline alumina. In another general embodiment, a method includes forming a first magnetic layer, forming a tunnel barrier layer above the first magnetic layer, and forming a second magnetic layer above the tunnel barrier layer. The tunnel barrier layer includes crystalline alumina. The tunnel barrier layer is formed at a temperature of less than 100 degrees centigrade.
