9319367巴尼克技术摘要：将用核磁共振技术研究气体插入型改性硬磁系统(包括A-钐铁合金)磁化强度和居里温度升高的微观原因。通过在间隙位引入C和/或N可以改善磁性能。结果将与中子衍射和Moessbauer研究得出的结论相关联。非技术摘要：最近已经证实，某些富含过渡金属的材料的磁性随着碳和/或氮等气体的添加而显著改善。这一尚未解释的发现不仅对基础科学特别有意义，而且对改进的磁记录头的发展也有特别的意义。结果将与以前用其他技术测量的结果进行比较，特别是中子散射和Moessbauer研究。***

9319367 Budnick Technical abstract: The microscopic origin of the increase of magnetization and Curie temperature in gas insertion modified hard magnetic systems (including A samarium iron alloy) will be studied with nuclear magnetic resonance techniques. The improved magnetic properties can be achieved by the introduction of C and/or N into interstitial sites. Results will be correlated with conclusions drawn from neutron diffraction and Moessbauer studies. Non-technical abstract: It has been recently established that the magnetic properties of certain transition metal rich materials were significantly improved with the addition of gases such as carbon and/or nitrogen. This, as yet unexplained, discovery is of special interest to fundamental science but also to the development of improved magnetic recording heads. The results will be compared to previous measurements with other techniques, notably neutron scattering and Moessbauer studies. ***
