Author(s): T. Mori, K. Iwamoto, S. Kushibiki, H. Honda, H. Matsumoto, N. Toyota, M. A. Avila, K. Suekuni, and T. Takabatake We present optical conductivity studies of the type-I clathrate Ba_{8} Ga_{16} Sn_{30} , using a terahertz time-domain spectrometer (0.3–3.0 THz). The lowest-lying spectral peak at 0.72 THz due to the Ba(2) ion’s off-center vibration in the oversized cage shows a drastic and anomalous temperat... [Phys. Rev.
