Imprinting Chirality on a Conventional Superconductor

Abstract

Chiral imprinting is demonstrated in metals, semiconductors, and oxides. In these cases, the mixing of chiral molecules with the studied material changes the structure of the hybrid system, resulting in new physical properties. In this work, chirality is imprinted on lead (Pb) that is a conventional singlet s‐wave superconductor. The hybrid material exhibits an increase in the critical field ( H C ) and a wider temperature phase transition under in‐plane magnetic fields. These results demonstrate a method for locally altering the magnetic‐response properties of conventional superconductors.
