We report on magneto-optical trapping of fermionic {sup 53}Cr atoms. A Zeeman-slowed atomic beam provides loading rates up to 3x10{sup 6} s{sup -1}. We present systematic characterization of the magneto-optical trap (MOT). We obtain up to 5x10{sup 5} atoms in the steady-state MOT. The atoms radiatively decay from the excited P state into metastable D states, and, due to the large dipolar magnetic moment of chromium atoms in these states, they can remain magnetically trapped in the quadrupole field gradient of the MOT. We study the accumulation of metastable {sup 53}Cr atoms in this magnetic trap. We also report on the simultaneous magneto-optical trapping of bosonic {sup 52}Cr and fermionic {sup 53}Cr atoms. Finally, we characterize the light-assisted collision losses in this Bose-Fermi cold mixture.
