Contrasting classes of superconductors

I think the Figure below is a really nice one which compares the variation of the superconducting order parameter on the Fermi surfaces for four different classes of superconductor:
a. elemental
b. cuprates
c. MgB2
d. iron pnictides

The figure is taken from a 2010 Perspective in Nature by Igor Mazin.

A recent post considered how to unify b. and d.

The legacy of 40 years of cuprate superconductivity

In February 1986, Bednorz and Müller made a stunning discovery: superconductivity at a temperature of 35 K in a doped copper oxide (cuprate)...
