Field-induced superconductivity occurs when an applied magnetic field increases or induces superconductivity. In a new report published in Science Advances, Joshua J. Sanchez and a team of scientists applied stress as a switch between a field tunable superconducting state and a robust non-field tunable state, to mark the first demonstration of a strain-tunable, superconducting spin valve with infinite magnetoresistance.

The scientists combined tunable uniaxial stress and applied a magnetic field on the ferromagnetic superconductor to shift the field-induced zero resistance . Using X-ray diffraction, and spectroscopy measurements under stress, the team proposed the origin of field-induced superconductivity to result from a new mechanism known as the dipolar fold.
