Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductivity is one of the exotic superconducting states which have not been directly observed experimentally. The in-plane high-magnetic-field and ultra-low-temperature phase of the heavy-electron superconductor CeCoIn5 is the subject of active debate as a promising candidate phase for the FFLO state. However, conclusive experimental evidence has not yet been obtained. To address this, we have developed the in-plane high magnetic field and ultra-low-temperature scanning tunneling microscope combined with the 14 T superconducting magnet and the 3He-4He dilution refrigerator, aiming to observe the unique spatially modulated superconducting properties of the FFLO phase in real space.
