Abstract (EN): <jats:title>Abstract</jats:title><jats:p>The properties of the acoustic modes are sensitive to magnetic activity. The unprecedented long-term <jats:italic>Kepler</jats:italic> photometry, thus, allows stellar magnetic cycles to be studied through asteroseismology. We search for signatures of magnetic cycles in the seismic data of <jats:italic>Kepler</jats:italic> solar-type stars. We find evidence for periodic variations in the acoustic properties of about half of the 87 analysed stars. In these proceedings, we highlight the results obtained for two such stars, namely KIC 8006161 and KIC 5184732.</jats:p>
