  New magnetic Ap stars with split Zeeman components are presented. These stars
were discovered from observations with the FEROS spectrograph at the ESO 2.2-m
telescope. Fifteen new magnetic stars are analysed here. Several stars with
very strong magnetic fields were found, including HD\,70702 with a 15-kG, and
HD\,168767 with a 16.5-kG magnetic field strength measured using split Zeeman
components of spectral lines and by comparison with synthetic calculations. The
physical parameters of the stars were estimated from photometric and
spectroscopic data. Together with previously published results for stars with
strong magnetic fields, the relationship between magnetic field strength and
rotation period is discussed.
