                      Haas–van Alphen (dHvA) frequencies of the torque
                      magnetization in the itinerant antiferromagnet CrB2 at
                      temperatures down to 0.3 K and magnetic fields up to 14 T.
                      Comparison with the Fermi surface calculations considering
                      an incommensurate cycloidal magnetic order suggests that two
                      of the observed dHvA oscillations arise from electronlike
                      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 strong 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. In the view that
                      the B-p bands are at the heart of conventional
                      high-temperature superconductivity in the isostructural
                      MgB2, we consider possible implications of our findings for
                      nonmagnetic CrB2 and an interplay of itinerant
                      antiferromagnetism with superconductivity.},
