中文摘要 | We present the first measurement on the Nernst effect in the normal state of the odd-parity, spin-triplet superconductor Sr(2)RuO(4). Below 100 K, the Nernst signal was found to be negative, large, and, as a function of magnetic field, nonlinear. Its magnitude increases with the decreasing temperature until reaching a maximum around T(*) approximate to 20-25 K, below which it starts to decrease linearly as a function of temperature. The large value of the Nernst signal appears to be related to the multiband nature of the normal state and the nonlinearity to band-dependent magnetic fluctuation in Sr(2)RuO(4). We argue that the sharp decrease in the Nernst signal below T(*) is due to the suppression of quasiparticle scattering and the emergence of band-dependent coherence in the normal state. |
