Abstract
We present Andreev spectroscopy data, down to 80Â mK and up to 2.5Â T, taken with ballistic point contacts on single crystals of the heavy-fermion superconductor PrOs4Sb12. Spectral dependences on magnetic field H and temperature T were studied to track how the order-parameter symmetry evolves and thus map out the H-T phase diagram. We observe a field-driven change in the nodality of the order-parameter suggesting that there are multiple superconducting phases, with different pairing symmetries, in PrOs4Sb12.
