Pressure suppression of unconventional charge-density-wave state in PrRu4P12 studied by optical conductivity

H. Okamura, N. Ohta, A. Takigawa +12

Optical conductivity s(w) of PrRu4P12 has been studied under high pressure to 14 GPa, at low temperatures to 8 K, and at photon energies 12 meV-1.1 eV. The energy gap in s(w) at am…
