We report giant bulk rectification in the bulk trigonal superconductor PbTaSe_{2}. Nonreciprocal magnetotransport originating from a vortex ratchet motion was successfully observed. showing a significant enhancement during the superconducting transition. which is considered a model behavior for three-dimensional noncentrosymmetric superconductors with strong vortex pinning. https://www.marketingjeunesse.com/product-category/straight-works/
