Abstract

The superconducting-state heat capacity of Na_0.3CoO₂ was investigated. The results shows the presence of two distinctly different energy gaps and line nodes. The small gap contribution obtained in this way was very similar to one for Sr₂ruO₄. It was observed that the vortex-state data, showed strong fluctuation effects.
