  The results of a search for supersymmetry in events with large missing
transverse momentum and heavy flavour jets using an integrated luminosity
corresponding to 2.05 fb^-1 of pp collisions at sqrt(s) = 7 TeV recorded with
the ATLAS detector at the Large Hadron Collider are reported. No significant
excess is observed with respect to the prediction for Standard Model processes.
Results are interpreted in a variety of R-parity conserving models in which
scalar bottoms and tops are the only scalar quarks to appear in the gluino
decay cascade, and in an SO(10) model framework. Gluino masses up to 600-900
GeV are excluded, depending on the model considered.
