The most recent results of the searches for direct production of third generation squarks with the ATLAS detector are presented. All the selected analyses use 21 fb−1 of pp collisions at √s = 8 TeV and follow the assumptions of a Minimal Supersymmetric extension of the Standard Model of Particle Physics where the R-parity is conserved and the lightest supersymmetric particle (LSP) is the lightest neutralino. Naturalness considerations require that the partners of the top and bottom quarks are light (O(1 TeV)) and hence have a relatively high production cross-section at the LHC. Since no deviations from the Standard Model predictions are observed, limits are set for different mass hierarchies and mass relations between the bottom and top squarks and the lightest chargino and neutralino.
