摘要
The temperature dependence of the intensity and frequency of two intense features in the Raman spectrum of kappa-(BEDT-TTF)(2)Cu(NCS)(2) have been measured. The spectra were taken with a Fourier Raman spectrometer equipped with an infrared laser. The two lines are due to a strongly resonant nu(9)(A(g)) doublet, and a sharp line due to nu(60) (B-3g). The frequencies of these modes are observed to soften below 80 K, in the temperature range where antiferromagnetic spin fluctuations have been observed with NMR, providing evidence of interactions between the phonons and the magnetism.
