Scientific paper

We present new results of our ongoing project to find new magnetic stars in stellar groups and open clusters. Observations are carried out at the 6-m and 1-m telescopes of the Special Astrophysical Observatory. Candidates are selected by analyzing the profiles of the [lambda]5200 broad, continuum features with low resolution spectra (a modification of the Cramer & Maeder method). These candidates are observed then with high resolution and a Zeeman analyzer. We present the measurements of 6 new magnetic stars and discuss results for 2 stars with outstanding magnetic fields. To date we found 31 new magnetic stars, listed for the most part in catalogues of stellar groups. Several stars have very strong magnetic fields, among them is the SrCrEu star HD 178892 with a surface magnetic field Bs≥ 20 kG.
