Description	We report the angular dependence of three distinct de Haas–van Alphen (dHvA) frequencies in the itinerant antiferromagnet CrB2 at temperatures down to 0.3 K. Comparison with the Fermi surface calculations considering an incommensurate cycloidal magnetic order suggests that two of the observed dHvA oscillations arise from Fermi surface sheets formed by bands with strong B-px,y character. The third orbit could correspond to a Cr-d derived Fermi surface sheet. The measured effective masses of these Fermi surface sheets display enhancements of a factor of about 2 over the calculated band masses which can be attributed to electron-phonon coupling and electronic correlations. Signatures of further heavy d-electron bands that are predicted by the calculations are not observed in the temperature and field range studied.
