  • Patent number: 9960346
    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.

  • Publication number: 20170018705
    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.

  • Patent number: 7556086
    Abstract: Device for enhancing cooling of electronic circuit components that is substantially or fully independent of orientation. A thin profile thermosyphon heat spreader mounted to an electronics package comprises a central evaporator in hydraulic communication with a peripheral condenser, both at least partially filled with liquid coolant. A very high effective thermal conductivity results. Performance is optimized by keeping the evaporator substantially full at all orientations while leaving a void for accumulation of vapor in the condenser. A cover plate and a parallel base plate of generally similar dimension form the evaporator and condenser. Optionally, an opening in the base plate is sealed against the electronics package and places the heat-dissipating component in direct contact with the liquid coolant. Alternatively, the base plate may be formed with the electronics package from a single piece of material. A boiling enhancement structure is provided in the evaporator to encourage vapor bubble nucleation.
