Christopher Woodgate

PhD Title: Physics of magnets and the arrangements of atoms comprising them

PhD Supervisor: Julie Staunton

Background

As an undergraduate, I studied Maths and Physics at the University of Warwick, graduating in July 2019 with 1st class honours (BSc MMathPhys). My final year project supervisor was Dr Nicholas d'Ambrumenil; we looked at some aspects of the physics of the frustrated antiferromagnetic system of Gadolinium Gallium Garnet.

Research Interests

I am now in the second year of the HetSys programme, working under the supervision of Prof. Julie Staunton. We study the physics of multicomponent alloys, using ab initio calculations and atomistic modelling to predict the nature of ordered structures and their properties.

Initially we looked at the binary alloy Fe1-x Gax , commonly referred to as 'Galfenol'. This is a highly magnetostrictive material and has applications in the design of sensors and actuators. I studied the nature of atomic short-range order in the material which, in collaboration with George Marchant, we used to explain the Ga-concentration dependence of the material's magnetoelastic constant.

We have now moved on to looking at the nature of atomic short range order in multi-component alloys, with a particular focus on the so-called High-Entropy Alloys (HEAs). We use a combination of KKR-CPA calculations, a linear response theory, and atomistic simulations.

Outreach and Public Engagement

I was the lead host for the first series of the HetSys podcast series, Multiscale Musings, and for the second series have taken on a leadership role. We interview academics with research interests in the area of predictive modelling, talking to them about their hobbies and interests, and also details of their research. The podcast is aimed at a general audience.

Hobbies and Interests

I am heavily involved with the University of Warwick Archery Club. For the academic years 2019/20 and 2020/21 I am the club Equipment Officer, but in the past I have also help the role of Team Captain. I enjoy both the competitive and social aspects of the sport, and am also a qualified Archery GB Level 2 coach.
