The observation of ordering in GaAsP alloys is reported. The CuPt structure with ordering along the <111> directions on the anion sublattice was observed by transmission electron diffraction patterns in GaAs1-xPx alloys at compositions of x=0.3 and 0.4. Only two of the four CuPt variants were observed. The degree of ordering along the 1/2[111] direction is higher than for the other variant, ordered along the 1/2[111] direction. In addition, the degree of ordering decreases when x is reduced from 0.4 to 0.3.
