First Order Reversal Curve Analysis on Superconductors

The magnetometric technique of First Order Reversal Curve (FORC) analysis, applicable to hysteretic systems, is introduced to the study of superconducting samples. Some typical superconducting structures in FORC diagram are identified, and the reversible and irreversible components are isolated, allowing the identification of typical magnetic features for superconductors and therefore extending the usefulness of the technique to more complex systems like hybrid S/N, S/F, and spin valves by improving the characterization of interactions among the components.
