Dr Daniel A. Mayoh

My Research Profile


In 2015 I joined the Superconductivity and Magnetism group at the University of Warwick as a postgraduate research student where I undertook my PhD under the supervision of Martin Lees. I completed my MPhys Physics degree at the University of St Andrews in 2015.

I rejoined the Superconductivity and Magnetism group at the University of Warwick in the summer of 2019 as a research fellow, where I work with Prof. Geetha Balakrishnan, as a part of The Skyrmion Project.

Research Interests


My current research focuses on skyrmionic materials. In particular the synthesis and characterisation of single-crystal samples that host skyrmions.

During my PhD, my research was focused on noncentrosymmetric superconducting systems. In particular, I am interested in superconductors where time-reversal symmetry breaking is also observed. My work involves the synthesis of high-quality polycrystalline and single-crystal samples that can then be characterised using a variety of low-temperature thermodynamic, transport and magnetisation measurements. I also use international central facilities to carry neutron scattering, muon spectroscopy, and high magnetic field experiments.

Teaching Duties


I was was a demonstrator and marker for the 1st Year Physics Teaching Laboratory and 1st Year Electronics Laboratory between 2015 and 2019. I was honoured to be selected as a commendee for the Warwick Awards for Teaching Excellence for Postgraduates who Teach 2018.

Public Engagement, Outreach and Widening Participation


I help run a series of workshops on superconducting 'levitation'. As part of this program, I deliver the workshops at the university of Warwick, local schools and at science events. The levitation workshop aims to explain the importance of superconductivity and magnetism in every day life. We demonstrate the stark changes that occur to the physical properties of materials when we cool them down using cryogenic liquids.
