%X In a superconducting material, electrical resistivity abruptly disappears below a critical temperature. Discovered in solid mercury in 1911, superconductivity remained an unsolvable riddle until 1957, when physicists Bardeen, Cooper, and Schrieffer developed a theory explaining the phenomenon (1). According to the Bardeen-Cooper-Schrieffer (BCS) scheme, superconductivity arises when electrons form pairs that behave in a way that allows current to flow with zero resistance. Then, in 1964, Fulde and Ferrell (2) and Larkin and Ovchinnikov (3) pointed out that in the presence of a magnetic field, a different type of superconducting electron pairs could form. However, despite the intense search, direct evidence of this Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting state has proven hard to find. On page 397 of this issue, Kinjo et al. (4) report the observation of FFLO-driven spin-density modulations in the layered perovskite Sr2RuO4—a system with its own peculiar history.
