Abstract
The paper presents the results of searching and studying magnetic fields of 4 chemically peculiar stars in the Pleiades open cluster and 21 CP stars in the kinematic group of the same name. Observations were carried out at the 6-m BTA SAO RAS telescope with a circular polarization analyzer. Four stars with anomalously strong silicon lines were previously specified in the Pleiades cluster. We did not find a magnetic field in any of them. The Pleiades group contains seven non-magnetic HgMn stars and 14 potentially magnetic Ap/Bp stars of various types. We detected or confirmed magnetic fields in eight objects. The fraction of magnetic CP stars is 57\(\%\) relative to Ap/Bp. Not a single object was found in the group, in which the longitudinal magnetic field \(B_{e}\) would exceed 2 kG.
