Warmest congratulations to Alex Eaton, who has won a Junior Research Fellowship at Sidney Sussex College - well done! A member of Suchitra's group, Alex carried out high precision quantum oscillation measurements at high magnetic fields in FeSb2, which showed that this unusual narrow-gap semiconductor features a large Fermi surface in its insulating bulk. Intriguingly, the Fermi surface signatures become very strong in the vicinity of a field-induced metamagnetic transition, which may help understand their origin. In a separate set of high field transport experiments, he was able to demonstrate the presence of metallic surface states in FeSb2. This is turning out to be a very interesting material, but - Alex - there are many others requesting your attention!
