In this short review, we report on the recently found growing experimental evidence for the existence of
Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) states in quasi-two-dimensional organic superconductors. At high
magnetic fields aligned parallel to the conducting organic layers, we observe an upturn of the upper critical field
beyond the Pauli limit, as evidenced by specific-heat and torque-magnetization measurements. Inside the superconducting
state a second thermodynamic transition emerges. These features appear only in a very narrow angular
region close to parallel-field orientation.
