An iron-based superconductor Fe(Se,Te) is a candidate material for exploring nonreciprocal superconducting transport owing to its large critical parameters and spin-orbit interaction. Here, the authors find a scaling relation of the superconducting diode efficiency in Fe(Se,Te)/FeTe heterostructure, revealing the role of asymmetric vortex pinning effect coupled to the spin-orbit interaction.
