Abstract
Superconductivity is a state of matter with many unique properties. Perhaps the most well known is that superconductors repel magnetic fields (Meissner effect), which leads to magnetic levitation. But surprisingly some unusual superconductors also appear to contain small internal magnetic fields, possibly due to Copper pairs of electrons forming bound states with non-zero angular momentum. One of the best known examples of this is the 1.5K superconductor Sr2RuO4. This material was discovered 30 years ago but still remains a mystery. In this talk I will explain some of this controversial history and some of our ongoing work on this problem.
About Physics colloquium
The Physics Colloquium series hosts a range of speakers from Australia and abroad. The series explores a variety of topics and everyone is welcome to come along. The seminars are open so there is no need to register your attendance.
If you would like to sign up for colloquium announcement emails, you can join the mailing list by sending a blank email to:
