Abstract
A search for CP violating effects in the mixing of neutral B mesons is performed using a sample of 4.1 million hadronic Z decays collected with the ALEPH detector from 1991 to 1995. By studying time-dependent asymmetries in flavour-tagged samples of semileptonic and fully inclusive b-hadron decays, two measurements of the semileptonic asymmetry $a_{\rm CP}$ are extracted. No evidence for CP violation is observed, and the combined value $a_{\rm CP}= -0.013 \pm 0.026$ is obtained.
