About

Mike Sumption serves as the associate director of the Center for Superconducting and Magnetic Materials, as well as the Superconducting Technology Center. Dr. Sumption’s background is in materials science and solid state physics. His area of research is materials physics with a concentration in superconductive, electronic, and magnetic materials, with particular interests in:

(i) high performance Nb3Sn, A15 phase formation, and transport properties,
(ii) MgB2 materials, with a focus on formation as well as dopant-induced enhancements of the upper critical fields and the related structural and transport properties,
(iii) Bi:2212 strands and their transport properties
(iv) nanoscale artificial pin structures in multilayer YBCO,
(v) magnetization, AC Losses, flux jumping, and current/field instabilities in superconducting strands,
(vi) flux pinning and connectivity in Nb3Sn and MgB2,
(vi) NbTi, Nb3Sn, Bi:2212, and YBCO-based cables in terms of loss, ICR, and current sharing related to HEP magnet applications.
