Title: | Nuclear spin relaxation due to motion on inequivalent sites: H diffusion on O and T sites in the face-centred cubic structure | Contributor(s): | Luo, Xinjun (author); Sholl, Colin (author) | Publication Date: | 2003 | DOI: | 10.1088/0953-8984/15/6/320 | Handle Link: | https://hdl.handle.net/1959.11/1646 | Abstract: | Magnetization recoveries for nuclear spin relaxation of like spins due to magnetic dipolar coupling and diffusion on inequivalent sites involve a sum of exponentials. The theory is applied to diffusion on octahedral and tetrahedral interstitial sites in the face-centred cubic structure. Monte Carlo simulations have been used to generate relaxation data for parameters typical for H in metals. It is found that only a single exponential would be observable in the high- and low-temperature limits, but that two-exponential recoveries could be observable in the vicinity of the maximum in the relaxation rate as a function of temperature. The Monte Carlo relaxation data has been fitted using a Bloembergen–Pound–Purcell (BPP) model to assess the accuracy of the BPP model. | Publication Type: | Journal Article | Source of Publication: | Journal of Physics: Condensed Matter, 15(6), p. 937-944 | Publisher: | Institute of Physics Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1361-648X 0953-8984 |
