Development of Next-Generation Memories and Sensors
Development of a magnetic sensor for magnetoencephalography with fT/Hz1/2 resolution at room temperature
Project details
We aim to develop a new magnetic sensor for brain imaging with sensitivity better than the resolution commercially available for dynamical detection of brain functions. Current techniques are limited in terms of sensitivity and/or require cooling with liquid helium. Here we will demonstrate the dynamic property of fT/Hz^1/2 sensitivity for magnetoencephalography to achieve dynamical brain imaging. In this project, the UKJapan teams aim to develop a new magnetic sensor operational at RT better than the current technology. The York team has demonstrated a linear response in magnetisation under a small magnetic field application in an antidot structure consisting of ferromagnetic Fe and insulating MgO nanoparticles. The Japanese team has also been working on magnetisation dynamics especially for magneto-optical and spin caloritronic applications. By combining these expertise, we plan to develop highly sensitive magnetic sensors for RT operation. The sensitivity and performance of the sensors will be evaluated by the Japanese team using their high-frequency measurement setup with precise temperature control. We plan to exchange our PhD students and PDRAs throughout the projects to allow them to learn complementary skills. We will also discuss the progress of our project with a sensor manufacturer in Japan through the existing collaboration of them.

On-chip racetrack memory
Project details
It is anticipated that the basic research and material science undertaken could lead to practical application and implementation on a 4-7 year timescale. This project will enable the PI to focus on demonstrating this new memory architecture with the access to the characterisation and on-chip implementation facilities in the Hitachi Cambridge Laboratory (HCL). This will encourage the exchange between York and HCL, and will further strengthen the relationship. Therefore this project will provide a great opportunity for the PI and his group to work with a worldleading industry.
