发明名称 Magnetic tunnel junctions
摘要 A magnetic tunnel junction includes a conductive first magnetic electrode that includes magnetic recording material. A conductive second magnetic electrode is spaced from the first electrode and includes magnetic reference material. A non-magnetic tunnel insulator material is between the first and second electrodes. The magnetic reference material of the second electrode includes a non-magnetic region comprising elemental iridium. The magnetic reference material includes a magnetic region comprising elemental cobalt or a cobalt-rich alloy between the non-magnetic region and the tunnel insulator material.

主权项 1. A magnetic tunnel junction, comprising: a conductive first magnetic electrode comprising magnetic recording material; a conductive second magnetic electrode spaced from the first electrode and comprising magnetic reference material; a non-magnetic tunnel insulator material between the first and second electrodes; and the magnetic reference material of the second electrode including a non-magnetic region comprising elemental iridium, the magnetic reference material including a magnetic region comprising elemental cobalt or a cobalt-rich alloy between the non-magnetic region and the tunnel insulator material, elemental Ta being between the elemental cobalt or cobalt-rich alloy and the tunnel insulator material, an alloy comprising Co, Fe, and B being between the elemental Ta and the tunnel insulator material.
