Patent number: 9846134Abstract: Systems and methods for spinwave-based metrology in accordance with embodiments of the disclosure involve generating and detecting spinwaves in a sample having a ferromagnetic material; and determining a material thickness, a material integrity measure, a presence of a manufacturing defect, a categorical type of manufacturing defect, and/or a manufacturing process statistic corresponding to spinwave behavior in the sample. In an embodiment, spinwaves are generated by way of concurrent exposure of a target measurement site of the sample to each of a bias magnetic field and radiation (e.g., microwave or radio frequency radiation) produced by a first set of integrated waveguides. A response signal corresponding to a behavior of spinwaves within the target measurement site can be generated by way of a second set of integrated waveguides.Type: GrantFiled: September 6, 2013Date of Patent: December 19, 2017Assignee: NATIONAL UNIVERSITY OF SINGAPOREInventors: Hyunsoo Yang, Sankha Subhra Mukherjee, Jae Hyun Kwon

Publication number: 20170270986Abstract: In one embodiment, a desirable (e.g., substantially 100%) SOT switching probability is achieved in a SOT device by applying in-plane input current as one or more pulses having a tuned pulse width. In the case of a single pulse, pulse width may be selected as a single tuned pulse width or a range of pulse widths that avoid a specific pulse width determined to cause a switch-back response. In the case of multiple pulses, pulse width, a time interval between pulses and other factors such as intensities may be selected to prevent a switch-back response. Further, SOT switching speed may be achieved by reducing incubation delay through modification of an external magnetic field or input current density applied to the SOT device.Type: ApplicationFiled: March 14, 2017Publication date: September 21, 2017Inventors: Jungbum Yoon, Jae Hyun Kwon, Hyunsoo Yang
