Neutronidiffraktio, often translated as neutron diffraction, is a powerful experimental technique used to determine the atomic and magnetic structure of materials. It relies on the wave-like nature of neutrons, which scatter elastically from the nuclei of atoms within a sample. By measuring the angles and intensities of these scattered neutrons, scientists can reconstruct a detailed picture of how atoms are arranged in both crystalline and non-crystalline materials.

The process involves directing a beam of neutrons, typically generated by a nuclear reactor or a spallation source, onto a sample. As the neutrons interact with the material, they are diffracted in specific directions according to Bragg's Law, analogous to how X-rays diffract. The key advantage of neutron diffraction over X-ray diffraction lies in the neutron's magnetic moment. This allows it to interact with the magnetic moments of unpaired electrons in atoms, making it exceptionally useful for studying magnetic structures, including the orientation and ordering of magnetic moments. Furthermore, neutrons are particularly sensitive to light elements like hydrogen, which are difficult to detect with X-rays. This makes neutron diffraction invaluable in fields such as condensed matter physics, materials science, chemistry, and biology for understanding material properties at the atomic level.
