  • Publication number: 20180166197
    Abstract: A material may include at least one of BixSe(1-x), BixTe(1-x), or SbxTe(1-x), where x is greater than 0 and less than 1. In some examples, the material exhibits a Spin Hall Angle of greater than 3.5 at room temperature. The disclosure also describes examples of devices that include a spin-orbit torque generating layer, in which the spin-orbit torque generating layer includes at least one of BixSe(1-x), BixTe(1-x), or SbxTe(1-x), where x is greater than 0 and less than 1. In some examples, the spin-orbit torque generating layer exhibits a Spin Hall Angle of greater than 3.5 at room temperature.

  • Publication number: 20180166500
    Abstract: This disclosure describes an example device that includes a first contact line, a second contact line, a spin-orbital coupling channel, and a magnet. The spin-orbital coupling channel is coupled to, and is positioned between, the first contact line and second contact line. The magnet is coupled to the spin-orbital coupling channel and positioned between the first contact line and the second contact line. A resistance of the magnet and spin-orbital coupling channel is a unidirectional magnetoresistance.

  • Publication number: 20170337983
    Abstract: In some examples, an electronic device comprising an input ferroelectric (FE) capacitor, an output FE capacitor, and a channel positioned beneath the input FE capacitor and positioned beneath the output FE capacitor. In some examples, the channel is configured to carry a magnetic signal from the input FE capacitor to the output FE capacitor to cause a voltage change at the output FE capacitor. In some examples, the electronic device further comprises a transistor-based drive circuit electrically connected to an output node of the output FE capacitor. In some examples, the transistor-based drive circuit is configured to deliver, based on the voltage change at the output FE capacitor, an output signal to an input node of a second device.

  • Patent number: 9660582
    Abstract: A device including a spin channel to transport a spin current, a nano-oscillator, and a magnetoresistive device that receives the spin current from the nano-oscillator. The nano-oscillator includes a magnetization state that oscillates between a first state and a second state in response to an input voltage or current. The oscillation of the nano-oscillator may induce the spin current within the spin channel. The magnetoresistive device includes a magnetization state that is set based at least in part on the received spin current.

  • Publication number: 20170082697
    Abstract: An article may include a substantially perpendicularly magnetized free layer having a first magnetic orientation in the absence of an applied magnetic field. The article may also include a spin Hall channel layer configured to conduct a spin current configured to subject the perpendicularly magnetized free layer to a magnetic switching torque and a substantially in-plane magnetized bias layer configured to bias the substantially perpendicularly magnetized free layer to a second magnetic orientation. The second magnetic orientation is different than the first magnetic orientation and is out of a plane of the substantially perpendicularly magnetized free layer.

  • Patent number: 9240799
    Abstract: A device including a conductive layer configured to output a spin-current based on an analog input value, a plurality of magnetoresistive devices, and an encoder configured to output a digital value. Each of the magnetoresistive devices may be configured to receive a different reference voltage on a first side and the spin-current on a second side. The magnetization state of each of the magnetoresistive devices is set by respective reference voltages and the spin-current. The encoder may include a plurality of digital bits that is a digital representation of the analog input value based on the magnetization states of the magnetoresistive devices.
