Micromagnetic Simulations of High-Speed Magnonic Devices

Lead Research Organisation: University of Exeter
Department Name: Engineering Computer Science and Maths


The propagation of precessional excitations of ordered spins in magnetic materials - so-called spin waves - in complex micromagnetic landscapes forms basis of magnonics - the recently emerged and rapidly developing field of magnetism. The ultimate idea is to implement spin waves within signal and data processing devices that would be faster, smarter and more energy efficient than those based on semiconductors. In this project, you will design and predict performance of novel spin wave ("magnonic") devices using advanced numerical modelling tools. The best designs will then be within prototype devices that will be fabricated using advanced lithography tools and tested using microwave measurements and time resolved microscopy.

Description Currently, a numerical technique for the simulation of nanoscale magnetic materials such as nanoscale spin wave devices which has benefits over existing techniques.

Also, a spin wave valve-like logic device which allows manipulation of the propagation of waves via an antenna magnet sitting upon a magnetic waveguide. Such a gate type device can be used in the magnetic analog to semi-conductor circuitry.
Exploitation Route Either experimentally fabricating the device or implemented into software for the numerical parts.
Sectors Digital/Communication/Information Technologies (including Software)
