Scientific paper

The estimations of the surface magnetic field Hs, microturbulent velocity and iron abundance derived by a curve of growth analysis are presented. The 9 Å/mm dispersion spectra of the 6-m telescope in the region λλ4000 - 4600 Å were used. The surface magnetic field strength Hs(Z, X) is estimated using also the photometric calibration with assumed effective temperature.
