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.

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.

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.

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.
