The Fe-chalcogenide superconductor FeTexSe1–x is an interesting material for studying the interaction between topology, superconductivity, and magnetism. Using nitrogen vacancy (NV) centers in diamond, researchers have achieved nanoscale quantum sensing and imaging of magnetic flux in exfoliated FeTexSe1–x flakes, revealing a strong correlation between superconductivity and ferromagnetism. This discovery paves the way for exploring exotic quantum transport phenomena and potential applications in solid-state quantum information technologies.
To enable wide-field imaging with dense NV ensembles, ensuring direct contact between the sample and the diamond surface is essential. The Quantum Foundry provides the expertise to fabricate engineered diamond plates optimized for imaging diverse materials, from 2D systems to large-scale magnetic films.
This groundbreaking work revolutionized quantum nanoscale sensing by using nitrogen-vacancy (NV) centers in diamonds. The innovative approach enabled highly sensitive magnetic imaging at the nanoscale.
