Abstract: A magnetic tunnel junction has a conductive first magnetic electrode comprising magnetic recording material. A conductive second magnetic electrode is spaced from the first electrode and comprises magnetic reference material. A non-magnetic tunnel insulator material is between the first and second electrodes. The magnetic recording material of the first electrode comprises a first magnetic region, a second magnetic region spaced from the first magnetic region, and a third magnetic region spaced from the first and second magnetic regions. A first non-magnetic insulator metal oxide-comprising region is between the first and second magnetic regions. A second non-magnetic insulator metal oxide-comprising region is between the second and third magnetic regions. Other embodiments are disclosed.

Abstract: Some embodiments include a magnetic tunnel junction comprising magnetic reference material having an iridium-containing region between a multi-layer stack and a polarizer region. Some embodiments include a magnetic tunnel junction having a conductive first magnetic electrode which contains magnetic recording material, a conductive second magnetic electrode spaced from the first electrode and which contains magnetic reference material, and a non-magnetic insulator material between the first and second electrodes. The magnetic reference material of the second electrode includes a first region containing a stack of cobalt alternating with one or more of platinum, palladium and nickel; includes an iridium-containing second region over the first region; and includes a cobalt-containing third region over the second region. The third region is directly against the non-magnetic insulator material.
