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.
