Flavour changing neutral currents and precision measurements of CP violation are investigated in ATLAS as probes to new physics beyond the standard model. This talk presents the most recent results on the search for the rare decay B0s → μ+μ-, as well as providing the latest update on the study of the different angular amplitudes contributing to flavour tagged B0s → J/ψ (μ+μ-)φ (K+K-) decays. The latter analysis measures the CP-violating phase φs, as well as the average Bs meson lifetime Γs and the decay width difference ΔΓs.
