20140327 – A material with high saturation magnetization with low magnetocrystalline anisotropy—and therefore low coercivity—is expressed as α″-Fe16(NxZ1-x)2 (Z= C, B, O). This first of its kind combination of magnetic properties results from adding carbon dopants to the interstitial position of an iron lattice, where saturation magnetization remains almost same, but magnetocrystalline anisotropy...

20160423 – A two-terminal memory device combines the spin Hall effect for switching/writing and unidirectional spin Hall magnetoresistance (USMR) for detection/reading. The memory device, with two-terminal write and read operations, acts like an MTJ but carries greater switching efficiency. To write, a strong pulse is applied across the device so that spins are generated by spin Hall effect in the... Read More

This design for spin based memory and logic devices is compatible with current standard CMOS technology. It can be incorporated with low energy, nonvolatile memory and logic structures and provides an alternative means to write data stored in... Read More
20150029 – A new method for fabricating chip inductors uses chemical deposition to prepare soft magnet material (including iron, nitrogen, and carbon, boron, or oxygen) on different substrates. The multi-layer structures are made with chemical vapor deposition (CVD) and liquid phase epitaxy (LPE). With giant saturation magnetization, this method obtains an integrated inductance with ideal soft... Read More
20100207 – A newly designed magnetic tunnel junction (MTJ) device features a fixed magnetic layer with magnetic anisotropy out of the film plane (e.g., a generally perpendicular magnetic anisotropy) with a tunnel barrier layer on one side of the fixed magnetic layer.

20170173 – Composite CoFeB/Gd/CoFeB and CoFeB/Gd/Heusler stacks with bulk perpendicular magnetic anisotropy (PMA) have antiferromagnetic coupled magnetic structures and therefore a very small saturated magnetization (Ms). These stacks feature bulk perpendicular magnetic anisotropy that could be prepared onto any kind of seed layers. The design offers advantages in selecting good spin Hall channel... Read More

The device includes 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 two states in response to an input... Read More
20160364 – An electronic spintronic-based circuit device transmits a voltage from an input to an output in an energy efficient, fast and low-power manner. The device is comprised of an input ferroelectric (FE) capacitor and an output FE capacitor, each magnetically coupled to a ferromagnetic (FM) channel beneath the capacitors. When the input FE capacitor receives an input signal, it causes a... Read More
20140063 – An optical interconnect can be used as the interconnect in spin-based computation and logic systems. The spin-optical interconnect scheme consists of a spin-to-optical transmitter and an optical-to-spin receiver, which are connected with multichannel, integrated optical waveguides or fibers. For data transmission, a spin-based signal is converted to an optical signal and transmitted via... Read More
