摘要
Motivated by recent experiments on the organic superconductor lambda-(BETS)(2)FeCl4 we study magnetic-field-induced superconductivity, from the point of view of current-density-functional theory. It is found that both Meissner and Pauli pair breaking are suppressed by an exchange-correlation contribution to the vector potential, arising at the sites of the magnetic ions.
