The large amount of Heavy Flavour data collected by the ATLAS experiment is potentially sensitive to New Physics, which may be found in the mixing of B meson states, or through processes that are naturally suppressed in the Standard Model. We present the most recent results on the measurement of the decay of the Bs into J/psi phi based on full data collected in LHC Run-1 and with updated flavour tagging improving the accuracy in the CP-violating phase phi_s. We also present the measurement of the decay time difference in the Bd system. The most recent results on the search for the rare decay Bs (B0) ->mu+mu- are presented as well as results on the angular distribution parameters AFB and FL describing the decay Bd -> K*mu+mu- -> K+pi-mu+mu-.
