Search for New Spin Density Wave State in CeRhIn5 caused by Fermi Surface Reconstruction

Abstract: CeRhIn5 shows the rich phase diagram with superconductivity, spin density wave and charge density wave. The appearance of the Fermi surface nesting inside the antiferromagnetic state is reported at around 30 T by the transport measurements. More recently, the charge density wave is reported in the same field range in the micro fabricated sample. It is claimed that the Fermi surface nesting is the indication of the localized-itinerant transition of Ce moment. If this is the case, a substantial change should present in the antiferromagnetic ordering and for the staggered moments. The purpose of this proposal is to examine the change of the spin density wave by using a neutron diffraction under the pulsed magnetic fields upto 40 T. Understanding of the interplay between the Fermi surface and the magnetic wave vector gives the essential to understand the quantum phase transition of CeRhIn5.
