4. 특강주제: How Well Does High Field Specific Heat Probe the Nodal Nature of the Multi-Band Iron Superconductors?
5. 초록: High field specific heat was first measured in 1982, when 'high field'
meant 17 T. Today, measurements up to 35 T are fairly routine, at least in
a few groups. Unfortunately, although some iron superconductors of
interest have their upper critical fields (Hc2) below 35 T - like the Co-
doped BaFe2-xCoxAs2, many do not. This talk will detail what specific heat
in field can tell us about the nodal behavior of the bands in these
interesting materials, and what questions such data leave unanswered.
Knowledge of the nodal behavior in a superconductor is a key to
understanding the pairing mechanism, and the details of the parameters
important for the coupling.
