Investigation of the Magnetic Phases of the New Ambient Pressure Heavy Fermion Superconductor Ce3PtIn11.
We recently were able to synthesize a new heavy Fermion compound Ce3PtIn11. This compound belongs to the same type family of Ce-based heavy fermion superconductors as CeRhIn5 (under pressure) and CeCoIn5 (ambient pressure). Experiments on high quality single crystals of Ce3PtIn11 revealed that at ambient pressure the compound exhibits two successive transitions at T1 = 2.2 K and TN = 2.05 K and below Tc = 0.32K enters into a superconducting state. We propose a neutron experiment on a stack of oriented single crystals in order to determine the magnetic structures of the – likely - incommensurate (T1), commensurate (TN) and superconducting (Tc) state at ambient pressure. By additionally determining the effective moment on the Ce-ion in each phase it can be concluded if magnetism is from local 4f moments which is of importance to the pairing mechanism of the Cooper pairs as well of the nature of the quantum critical point of this compound. In this view, Ce3PtIn11 might be unique, being the first known stoichiometric and full inversion symmetrical Ce-based heavy Fermion compound where superconductivity develops out of a local moment magnetic state at ambient pressure.
