If you have a question about this talk, please contact Elizabeth Blackburn.

I will discuss recent magnetotransport data on an underdoped high-temperature superconductor. To assist with the discussion I will first describe how one goes about mapping the Fermi surface of quasi-two-dimensional materials using high magnetic field measurements, focussing particularly on the technique of angle-dependent magnetoresistance. This will be illustrated using the results of earlier experiments on an organic superconductor, for which a full determination of the Fermi surface was possible. I then will contrast this with the more challenging measurements performed on YBa2Cu3O6+x and explain what conclusions can be drawn in this case.
