Field-induced superconductivity is a rare phenomenon where an applied magnetic field enhances or induces superconductivity. Here, we use applied stress as a control switch between a field-tunable superconducting state and a robust non–field-tunable state. This marks the first demonstration of a strain-tunable superconducting spin

At finite temperatures (say, at room temperature of ~300 K), the thermal energy makes them (i.e. the ions or atoms) vibrate around their equilibrium positions. Since these ions are part of a typical crystal structure, their vibrations are collective, with a large number of them being involved in any typical mode of vibration, which is characteristic of a given material.

Above this temperature, thermal energy breaks the Cooper pairs, and the material reverts to a normal conductive state. 4. Meissner Effect.
