概要
- 論文の詳細を見る
We have carried out nuclear quadrupole resonance (NQR) measurements in the filled skutterudite compounds Pr(Os_<1-x>Ru_x)_4Sb_<12> (x=0.1, 0.2), in order to gain insights into the symmetry of the superconducting gap function. Upon replacing Os with Ru, the spin-lattice relaxation rate 1/T_1 becomes proportional to temperature(T) at low T far below T_c, and the magnitude of (1/T_1T)_<low-T> increases with increasing Ru content. These results indicate that a finite density of states is induced at the Fermi level by the impurity, and thus suggest that there exist nodes in the gap function of PrOs_4Sb_<12>.
