Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to search for magnetic fluctuations and the existence of a superconductivity-induced spin resonance in this material. The objective is to find out whether or not this material exhibits the same type of spin dynamics as other Fe-based superconductors. This is important since antiferromagnetic spin fluctuations are believed to play a role in superconductivity in the Fe-based superconductors. The measurements will be performed on a polycrystalline sample at a series of temperatures from below to above Tc.
