AbstractWe present the first results of directional point-contact spectroscopy in high-quality CaC6 samples both along the ab plane and in the c-axis direction. The superconducting gap Delta(0), systematically obtained by fitting the Andreev-reflection conductance curves with the single-band Blonder-Tinkham-Klapwijk (BTK) model, presents two different distributions in the two directions of the main current injection, peaked at 1.36 and 1.7 meV, respectively. By ab-initio calculations of the Andreev-reflection conductance spectra, we show that the experimental results are in good agreement with the recent predictions of an anisotropic gap in CaC6.
