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.
