  We report the results of our study of magnetic fields in a sample of 15 Be
stars using spectropolarimetric data obtained at the European Southern
Observatory with the multi-mode instrument FORS1 installed at the 8m Kueyen
telescope. We detect weak photospheric magnetic fields in four stars, HD56014,
HD148184, HD155806, and HD181615. We note that for HD181615 the evolutionary
status is not obvious due to the fact that it is a binary system currently
observed in the initial rapid phase of mass exchange between the two
components. Further, we notify the possible presence of distinct circular
polarisation features in the circumstellar components of Ca II H&K in three
stars, HD58011, HD117357, and HD181615, hinting at a probable presence of
magnetic fields in the circumstellar mass loss disks of these stars. We
emphasize the need for future spectropolarimetric observations of Be stars with
detected magnetic fields to study the temporal evolution of their magnetic
fields and the correlation of magnetic field properties with dynamical
phenomena taking place in the gaseous circumstellar disks of these stars.
