2847 20160701171711.0 ASTROimport-1004 Hubrig, S. 2011 Magnetic Fields of Hot Pulsating Stars In spite of recent detections of magnetic fields in a number of ß Cephei and slowly pulsating B (SPB) stars, their impact on stellar rotation, pulsations, and element diffusion is not sufficiently studied yet. One reason for this is the lack of knowledge of rotation periods, magnetic field strength distribution and temporal variability, and field geometry. New longitudinal field measurements of four ß Cephei and candidate ß Cephei stars, and two SPB stars were acquired with the FORS2 at the VLT. These measurements allowed us to carry out a search for rotation periods and to constrain magnetic field geometry for a few stars in our sample. Ilyin, I. Schöller, M. Morel, T. Briquet, M.
