Claim Text:
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 insulator material between the first and second electrodes; the magnetic recording material of the first electrode comprising a set having an iridium-containing region between a pair of non-iridium-containing regions; wherein the magnetic recording material of the first electrode comprises an uppermost region containing Co and Fe, with said uppermost region being directly adjacent to the non-magnetic insulator material; and wherein said set does not include the uppermost region as one of the non-iridium-containing regions of said pair; wherein said set includes a first crystalline lattice; wherein said uppermost region comprises a second crystalline lattice different from said first crystalline lattice; and wherein the uppermost region is spaced from the set by a buffer material.
