Abstract
A magnetic tunnel junction (MTJ) structure is of the type having a tunnel barrier positioned between a fixed ferromagnetic layer and a free ferromagnetic layer, the tunnel barrier includes a first barrier layer contacting either the fixed ferromagnetic layer or the free ferromagnetic layer. The first barrier layer transmits a high spin polarization and is selected from the group consisting of metal oxides, metal nitrides, and metal oxynitrides. The second barrier layer, which contacts the first barrier layer, has a low barrier height and is selected from the group consisting of metal oxides, metal nitrides, and metal oxynitrides.
