Competition between Superconductor – Ferromagnetic stray magnetic fields in YBa2Cu3O7−x films pierced with Co nano-rods

Abstract Superconductivity and ferromagnetism are two antagonistic phenomena that combined can lead to a rich phenomenology of interactions, resulting in novel physical properties and unique functionalities. Here we propose an original hybrid system formed by a high-temperature superconducting film,...
