Experimental and theoretical x-ray magnetic circular dichroism studies at the uranium M₄ and M₅ edges are reported. The results show that the orbital-to-spin moment ratio is of comparable value, ć_L/ć_s÷-2, for both compounds; however, the moments in UCoAl are strongly reduced with respect to UPtAl. The FLAPW method was used for electronic structure calculation.
