Abstract
This work studies the temperature evolution of the thermodynamic critical field ${B}_{\mathrm{c}}$ in type-I noncentrosymmetric superconductor BeAu. The authors find that the single-gap scenario cannot describe ${B}_{\mathrm{c}}$ and two different types of superconducting order parameters are needed.
