| dc.description | The temperature dependent frequency shifts of the Raman active G-band have recently been measured by R.Walter et al. for single-walled carbon nanotubes containing different concentrations of the magnetic impurity Ni:Co. These Raman data can be quantitatively explained by magnetic pair-breaking effect on a superconductor with a mean-field transition temperature T_c0 of 645 K, in excellent agreement with independent electrical transport and single-particle tunneling data. We suggest that such high-T_c superconductivity might arise from the pairing interaction mediated mainly by undamped acoustic plasmons in a quasi-one-dimensional electronic system. | |
