## Abstract

Motivated by recent experiments on the organic superconductor $\\lambda-(BETS)\_2FeCl\_4$ we study the Jaccarino-Peter effect (JPE), the earliest example of magnetic-field-induced superconductivity, from the point of view of current-density-functional theory. It is found that both Meissner (diamagnetic) and Pauli (paramagnetic) pair breaking are suppressed by an exchange-correlation contribution to the vector potential, arising at the sites of the magnetic ions. This explains a number of otherwise puzzling experimental observations, and sheds new light on earlier theories of the JPE.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
