We report the observation of nuclear resonant diffraction of synchrotron radiation from a ⁵⁷Fe/Cr multilayer. The multilayer consists of 25 ⁵⁷Fe(17 Å)/Cr(10 Å) bilayers with the Cr layer thickness chosen so as to exhibit antiferromagnetic (AF) coupling of the ⁵⁷Fe layers. Because of the AF alignment of the layers, the magnetic periodicity of the multilayer is twice the electronic periodicity, resulting in a pure nuclear Bragg reflection that appears during nuclear resonant diffraction. The pure nuclear Bragg reflection presents a means of filtering synchrotron radiation to the level of 10^–8 eV at the nuclear resonance energy of 14.4 keV.
