Job summary

This PDRA position is part of the NERC project “Thermochemical remanent magnetisations: How do they affect ancient magnetic field intensities from the Earth and Solar System?” (http://gotw.nerc.ac.uk/list_full.asp?pcode=NE%2FV001388%2F1). The aim of this NERC project is to finally quantify how natural magnetic systems are affected by high-temperature exsolution.

Natural magnetic systems often contain solid-solutions of titanium-rich iron oxides. These exsolve/unmix on cooling. Traditionally it is assumed that this unmixing occurs above the magnetic ordering temperature (the Curie temperature), however, there is much evidence to suggest that it occurs blow the Curie temperature, maybe in >50% of all magnetic recordings by rocks. We simply do not know how reliable and meaningful these remanent magnetisations recorded by rocks where unmixing is occurring blow the Curie temperature. It is the aim of this study to make the first detailed magnetic images of these processes, by conducting high-temperature nanometric magnetic images of in-situ exsolution using protocols previously developed by us (https://advances.sciencemag.org/content/2/4/e1501801).

The aim of the NERC proposal is to understand the physical process, and then to build a numerical model using micromagnetic methods (https://www.pnas.org/content/116/6/1984/tab-article-info). This work is at the forefront of our understanding of magnetic recording fidelity of natural systems, and marks potentially the biggest breakthrough in over 50 years.

This PDRA position at Imperial will determine these nanometric distributions under the guidance of Adrian Muxworthy, Josh Einsle, Trevor Almeida and Richard Harrison, whilst the numerical aspects of the project will be undertaken at Edinburgh.

Duties and responsibilities

Working with the NERC project PI Adrian Muxworthy (Imperial), Co-Is Wyn Williams (Edinburgh), Richard Harrison (Cambridge) and Josh Einsle (Glasgow), as well as Project Partners Karl Fabian (Norway), Trevor Almeida (Grenoble), Valera Shcherbakov (Russia) and Yuji Yamamoto (Japan), you will determine and understand the magnetic recording fidelity of natural magnetic minerals as they undergo high-temperature exsolution. You will do this using a combination of nanometric magnetic imaging using TEMs plus using FIB-SEM nanotomography and 3D chemical mapping (CITE).

 

Essential requirements

At Research Associate Level: A PhD in Material Science, Earth Science or Physics or equivalent research, industrial or commercial experience 

At Research Assistant Level: Near completion of a PhD (or equivalent) in Material Science, Earth Science or Physics or equivalent research, industrial or commercial experience 

In addition, you must meet the following criteria: 

  • You will have extensive knowledge of detailed knowledge of a range of electron microscopy methods including TEM magnetic imaging and FIB slice-and-view, and sample preparation for these methods. 
  • You will have published or submitted several first author peer-reviewed scientific papers.

Further information

This is a fixed term contract for up to 36 months until 31st October 2023 

Candidates who have not yet been officially awarded their PhD will be appointed as Research Assistant salary range £35,477 - £38,566 per annum.
