A search for supersymmetric partners of top quarks decaying as t ~ 1 ?c? ~ 0 1 and supersymmetric partners of charm quarks decaying as c ~ 1 ?c? ~ 0 1, where ? ~ 0 1 is the lightest neutralino, is presented. The search uses 36.1 fb -1 pp collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider and is performed in final states with jets identified as containing charm hadrons. Assuming a 100% branching ratio to c? ~ 0 1, top and charm squarks with masses up to 850 GeV are excluded at 95% confidence level for a massless lightest neutralino. For m t ~ 1 ,c ~ 1 -m ? ~ 0 1 < 100 GeV, top and charm squark masses up to 500 GeV are excluded.
