Spin and orbital magnetic moments of the L21-type Co 2FeGa Heusler alloy have been investigated using x-ray magnetic circular dichroism spectra in the soft x-ray region. From the spectra of the L2,3-edge of Co and Fe, the ratios of the orbital magnetic moment to the spin magnetic moment Morb/Mspin are estimated to be 0.06 for Co and 0.02 for Fe, in agreement with the available theoretical values. The orbital magnetic moments of these two elements are small in line with theoretical results, reflecting the high symmetry of the L21-type crystal structure. Furthermore, it has been confirmed that the magnetic moment of Ga is induced in the present alloy.
