Figure 2From: Short-range spin-phonon coupling in in-plane CuO nanowires: a low-temperature Raman investigationSeries of Raman spectra taken at various temperatures of CuO nanowires with a mean average diameter < d > = 120 ± 8 nm. Two main phonon modes corresponding to the Ag and Bg1 symmetries, respectively, are revealed. As the temperature was reduced to143 K, a well-defined peak at 238 cm−1 developed, signifying the spin-phonon coupling.Back to article page
