Abstract Nonreciprocal charge transport phenomena are widely studied in two-dimensional superconductors. which demonstrate unidirectional-anisotropy magnetoresistances as a result of symmetry breaking. Here. we report a strong nonreciprocal transport phenomenon in superconducting CsV3Sb5 thin flakes. https://www.chiggate.com/satisfyer-pro-penguin-next-generation-on-sale/
