    • Dilute magnetism and vibrational entropy in Fe2Al5 

      Chi, Ji; Zheng, Xiang; Rodriguez, Sergio Y.; Li, Yang; Gou, Weiping; Rathnayaka, K. D. D.; Ross, Joseph H. Jr. (American Physical Society, 2010)
      Fe2Al5 contains a Fe-Al matrix through which are threaded disordered one-dimensional chains of overlapping Al sites. We report magnetic, nuclear-magnetic-resonance (NMR), and specific-heat measurements addressing its ...
    • NMR experiments and electronic structure calculations in Type-I BaAlGe clathrates 

      Gou, Weiping; Rodriguez, Sergio Y.; Li, Yang; Ross, Joseph H. Jr. (American Physical Society, 2009)
      We describe A27l NMR experiments on Ba8AlxGe46−x type-I clathrates coupled with ab initio computational studies. For x=16, calculated spectra determined by the ab initio results gave good agreement with the measurements, ...
    • NMR Study of Slow Atomic Motion in Sr8Ga16Ge30 Clathrate 

      Gou, Weiping; Li, Yang; Chi, Ji; Ross, Joseph H. Jr.; Beekman, M.; Nolas, G. S. (American Physical Society, 2005)
      The clathrates feature large cages of silicon, germanium, or tin, with guest atoms in the cage centers. Sr8Ga16Ge30 clathrate is interesting because of its thermoelectric efficiency, and its glasslike thermal conductivity ...
    • A nuclear magnetic resonance probe of group IV clathrates 

      Gou, Weiping (Texas A&M University, 2008-10-10)
      The clathrates feature large cages of silicon, germanium, or tin, with guest atoms in the cage centers. The group IV clathrates are interesting because of their thermoelectric efficiency, and their glasslike thermal ...
