Magnetically tunable supercurrent in dilute magnetic topological insulator-based Josephson junctions

P. Mandal, S. Mondal, et al.

This groundbreaking research by Pankaj Mandal and team explores the fascinating induction of a Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in Josephson junctions using the two-dimensional dilute magnetic topological insulator (Hg,Mn)Te. Their findings reveal intriguing re-entrant behaviors of critical current related to π-shifted ground states, driven by an enhanced Zeeman effect under an external magnetic field.
