Effect of single-ion magnet complexes [Er(HL)(L)]·4CHCl3·H2O on superconductor

Abstract

The interaction between molecular magnets and superconducting metal surfaces is a hot topic promising both for improving the properties of molecular magnets and for modifying superconductors. Controlled deposition of molecular magnet into superconducting matrix is promising for targeted information sensing. In this work, we develop a strategy for functionalizing Er³⁺-based molecular magnet by penetrating into superconducting matrix arrays. We demonstrate a change in the superconducting transition temperature upon contact between a superconductor and an Er³⁺-based molecular magnet. The proposed packing of different types of molecular magnets in superconducting composites enables targeted creation of a chemically engineered spin interface on a superconducting surface for spintronics and quantum computing.
