  • Patent number: 11594357
    Abstract: A base element for switching a magnetization state of a nanomagnet includes a heavy-metal nanostrip having a surface. The heavy-metal nanostrip includes at least a first layer including a heavy metal and a second layer which includes a different heavy-metal. A ferromagnetic nanomagnet is disposed adjacent to the surface. The ferromagnetic nanomagnet includes a shape having a long axis and a short axis, the ferromagnetic nanomagnet having both a perpendicular-to-the-plane anisotropy Hkz and an in-plane anisotropy Hkx and the ferromagnetic nanomagnet having a first magnetization equilibrium state and a second magnetization equilibrium state. The first magnetization equilibrium state or the second magnetization equilibrium state is settable by a flow of electrical charge through the heavy-metal nanostrip. A direction of the flow of electrical charge through the heavy-metal nanostrip includes an angle ? with respect to the short axis of the nanomagnet.

  • Patent number: 11378466
    Abstract: A hybrid integrated thermal sensor device includes a magnetic tunnel junction (MTJ) device electrically coupled in series with at least one CMOS transistor and disposed between a voltage rail terminal and a ground terminal. An output terminal is electrically coupled to a drain of the at least one CMOS transistor. The MTJ operates in an anti-parallel state and the output terminal provides a voltage indicative of a temperature of the MTJ device based on an MTJ antiparallel resistance. A distributed sensor network for real-time thermal mapping of an integrated circuit (IC) is also described.
