The ATLAS experiment has performed measurements of mixing and CP violation in the neutral B meson systems.
This talk will focus on the latest results from the ATLAS collaboration on CP violation in the B_s^0 —> J/psi phi decays.
Standard Model predicts the CP violating mixing phase, phi_s, to be very small and its SM value is very well constrained,
while in many new physics models large phi_s values are expected. Latest measurements of phi_s and several other parameters
describing the B_s^0 —> J/psi phi decays will be reported.
