Multiple Andreev reflections effect spectroscopy of LiFeAs single crystals: three superconducting order parameters and their temperature evolution

Highlights Three-gap superconductivity with possible momentum dependence (anisotropy) in LiFeAs. Temperature dependences of the superconducting gaps indicate a moderate interband coupling. Superconducting energy parameters scale with T c under minor lithium deficiency.
