Abstract
Previously, nuclear magnetic resonance experiments and diffusion calculations have indicated that the distribution of nitrogen atoms in a Y2Fe17Nx particle with intermediate N content is characterized by a nitrided region and an unnitrided region. In order to directly detect this two-region configuration, x-ray diffraction experiments have been carried out on systematically ground nitrogenated samples. Furthermore, x-ray diffraction and 89Y nuclear magnetic resonance on vacuum-annealed samples show that the two-region configuration is stable, and that the nitrogen atoms do not diffuse further into the particle. Thermal conductivity detection measurements indicate that only 5% of the inserted N atoms can be released by vacuum annealing at the nitrogenation temperature.
