  Motivated by recent interest in applications of the AdS/CFT correspondence to
condensed matter applications involving fermions, we present the supersymmetric
completion of the recent massive truncations of IIB supergravity on
Sasaki-Einstein manifolds. In particular, we reduce the fermionic sector of IIB
supergravity to obtain five dimensional N=2 supergravity coupled to one
hypermultiplet and one massive vector multiplet. The supersymmetry
transformations and equations of motion are presented and analyzed. Finally, a
particularly interesting truncation to N=2 supergravity coupled to a single
hypermultiplet is presented which is the supersymmetric completion of the
recently constructed bosonic theory dual to a 3+1 dimensional system exhibiting
a superconducting phase transition.
