PhD project opportunity: Multi-physics simulation of (ferromagnetic) nanostructures and devices

Eligibility: Please see http://www.ngcm.soton.ac.uk/studentships.html

The magnetisation of ferromagnets at length scales between 10 nm and 1000 nm is commonly described through the micromagnetic theory. These equations can be solved numerically to obtain the dynamics of the magnetisation and equilibrium configurations using packages such as OOMMF or Magpar, or the Southampton package Nmag.

With the advances in spin-torque transfer experiments (where the spin of conduction electrons is used to either probe of modify the magnetisation), the interplay of current density, magnetisation and also the temperature of the material have become important to consider these simulations. This project will focus on implementing and carrying out detailed studies of such multi-physics effects which matter for a range of existing and future devices and sensors [including spin-torque-transfer magnetic random access memory (STT-MRAM)]

Simultaneously, the code will be applied to interpret experimental results obtained in our laboratories, or those of our collaborators in industry and academia. The simulation will also be used to predict the outcome of future experiments through systematic device design optimisation.

Experience with any of the following will be advantageous but can be required as part of the project:

• Computational physics or computational materials science
• Programming experience
• Use of Linux
• Micromagnetic modelling (including use of Magpar, Nmag, OOMMF)

This project can be pursued through a PhD studentship in Complex Systems Simulations.
