A search for supersymmetric partners of top quarks decaying as t̃₁→ cχ̃⁰₁ and supersymmetric partners of charm quarks decaying as c̃₁ → cχ̃⁰₁, where χ̃⁰₁ 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 cχ̃⁰₁, top and charm squarks with masses up to 850 GeV are excluded at 95% confidence level for a massless lightest neutralino. For mt̃₁,c̃₁ - mχ̃⁰₁ < 100 GeV, top and charm squark masses up to 500 GeV are excluded.
