Abstract: A waveguide for spin wave (SW) transmission, a method of fabricating a waveguide for SW transmission, and a method of transmitting an SW. The waveguide comprises a plurality of nanomagnetic material elements, each nanomagnetic material element having a respective predetermined geometric shape such that each nanomagnetic material element exhibits a deterministic ground state initializable by a magnetic field applied across the waveguide; wherein the nanomagnetic material elements are disposed relative to each other for dipolar coupling between adjacent nanomagnetic material elements.

Abstract: In one embodiment, a capacitor-like structure is constructed that includes an RF co-sputtered TMO layer. The capacitor-like structure includes a first electrode (e.g., a bottom electrode) constructed of a first metal (e.g., Pt), a RF co-sputtered TMO layer on the first electrode including a first oxide and a second oxide (e.g., a RF co-sputtered Al2O3—NiO layer), and a second electrode constructed of a second metal (e.g., Pt) in contact with the co-sputtered TMO layer. The capacitor-like structure is resistively switchable due to formation and rupture of CFs through the RF co-sputtered TMO layer in response to application of a voltage between the first electrode and the second electrode. The RF co-sputtered TMO layer may be grown using at least one direct oxide target (e.g., a NiO target) in a noble gas (e.g., Ar) atmosphere.

Abstract: A device and a method of forming a device. The method comprises forming an oxide material film; forming two metal electrodes on the oxide material film, the two metal electrodes laterally spaced from each other such that an electric path between the two electrodes comprises at least a portion of the oxide material film; configuring the oxide material film such that a current-voltage characteristic of the device as measured via the two metal electrodes exhibits nonlinearity and rectification.

Abstract: A nanomagnetic structure and a method of fabricating a nanomagnetic structure. The nanomagnetic comprises two or more nanomagnetic material elements, each nanomagnetic material element having a respective predetermined geometric shape such that the nanomagnetic structure exhibits different stable ground states initializable by magnetic fields applied across the nanomagnetic structure in respective different directions; wherein the nanomagnetic material elements are disposed relative to each other such that the magnetic structure exhibits a difference in effective internal magnetic field strength between the different stable ground states. Advantageously, this variation in the internal magnetic field strength is the key for distinct dynamic response associated with the different magnetic ground states. Reconfigurable operation has been shown based on this magnetization dynamics in example embodiments.
