ResumoIt is shown by a brief calculation that the method of anisotropy measurement of $\ensuremath{\gamma}$-ray emission from spin-polarized nuclei is a useful tool to investigate multiple-spin-modulation waves which have been suggested to exist in several kinds of materials but have not yet been proven by definitive experimental evidence. An application of this method is made for a fcc antiferromagnetic Mn-Ni alloy and the first direct experimental evidence for a triple-Q spin-density wave is given.
