    • 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 and Mössbauer study of FeAl2 
      Chi, Ji; Li, Yang; Vagizov, F. G.; Goruganti, V.; Ross, Joseph H. Jr. (American Physical Society, 2005)
      We have used NMR and Mössbauer spectroscopy to investigate the magnetism and spin-glass behavior in FeAl2. The results show that the observed behavior can be interpreted as local-moment magnetism residing on the Fe sites. ...
    • 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 Fe-Al and Al20V2Eu intermetallics 
      Chi, Ji (2009-05-15)
      Al-rich Fe-Al systems (FeAl2, Fe2 Al5 and Fe4Al13) and Al20V2Eu have complicated structures with quasicrystal-like features making these materials potentially of interest for magnetic behavior. However, there is not much ...
