Takeya Comments: Ps file with figures Subj-class: Superconductivity; Strongly Correlated Electrons Evidence of gap anisotropy in superconducting YNi2B2C using directional point contact spectroscopy We present a study of the anisotropy in the superconducting energy gap in a single crystal of YNi2B2C (Tc~14.6K) using directional point contact spectroscopy. The superconducting energy gap at 2.7K, when measured for I||c, is 4.5 times larger than that for I||a. The energy gaps in the two directions also have different temperature dependences. Our results support a scenario with s+g like symmetry. http://xxx.lanl.gov/abs/cond-mat/0404322 |
