X‐ray measurements (specular and off‐specular X‐ray reflectivity, in‐plane and plane‐normal diffraction and truncation rod measurement) were carried out to characterize the epitaxial magnetic multilayers of yttrium iron garnet/gadolinium gallium garnet(GGG) on GGG substrate grown by the laser ablation deposition method. The perfection of the multilayer epitaxy can be better revealed in the observation of the 2 nd harmonics of superlattice peaks in the reflectivity measurement, the forbidden diffraction peaks and the truncation rod measurement.
