Spin-phonon coupled modes in the incommensurate phases of doped CuGeO${}_3$

K. Takehana, T. Takamasu, M. Hase +3

The doping effect of the folded phonon mode at 98 cm${}^{-1}$ was investigated on the Si-doped CuGeO${}_3$ by magneto-optical measurements in far-infrared (FIR) region under high magne…
