A PhD fellowship on experimental characterization and numerical modeling of magnetocaloric materials is now available at the Department of Energy Conversion and Storage, Technical University of Denmark.

This PhD position at DTU Energy will constitute the major part of a unique research project where we want to perform state-of-the-art in-situ experimental measurements of the most advanced magnetocaloric materials available and compare these to state-of-the-art numerical modelling tools also developed in the project. Currently, there is a significant discrepancy between measured properties and predictions by fundamental models; the measured properties are seen to be significantly weakened compared to those predicted by basic theory. In the project, advanced experiments available at DTU and at least two international partners (Imperial College London and Ames Laboratory, USA) will be conducted and subsequently compared with a state-of-the-art numerical modelling tool that embraces all the ongoing physics in these materials under dynamic conditions.

It will be the task of the PhD student to develop a high-resolution (both in time and space) infra-red measurement technique as a unique characterization tool at DTU Energy and use this together with several other unique techniques available to the project from the above-mentioned partners. These techniques include localized scanning Hall-probe imaging, micro-calorimetry and in-field XRD. The PhD student is therefore expected to spend between three and six months abroad in total visiting these laboratories.

This PhD position is a unique opportunity to get to work on and, in particular, develop cutting edge advanced characterization techniques while at the same time making an extremely important contribution to a promising research field on energy and environmentally friendly refrigeration technology based on solid-state refrigerants. Our research group is well-known for our outstanding numerical modelling tools developed over the past decade as well as our world-leading experimental techniques within multi-caloric materials research.

At the end of the PhD project we will hopefully have developed a theory for the finer mechanisms of bulk magnetocaloric materials and be able to point industry and other interested parties to the focus areas on the further development of high-end magnetocaloric materials. The main activity will take place at the Department of Energy Conversion and Storage at DTU Risø Campus.

Candidates should be highly motivated and must hold a master degree (or equivalent), preferably in a physics, engineering, chemistry or a materials science-related discipline.

Further qualifications:

  • Solid laboratory skills for using characterization equipment
  • Good understanding of realizing experimental setups
  • Good communication skills in English
  • Being able to work independently and in a team
Candidates with the following qualifications are preferred
  • Experience in numerical modeling
  • Experience with XRD and/or other materials characterization techniques
  • Experience with developing experimental setups and Labview or similar programs
  • Experience with Matlab or similar software
  • Experience with handling experimental data and data processing
Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility.
