Investigation of Multiple-q states around the Quantum Critical Point of URu2Si2 by Laue Diffraction in 40 T Pulsed Magnetic Fields II

Abstract: URu2Si2 has been examined intensively over the decades for the rich phase diagram including superconductivity, Hidden Order and multiple magnetic phases appearing around the quantum critical point (QCP). Despite its uniqueness, the QCP is located around a magnetic field of 35 T and neutron diffraction was impossible. In RB1710307 at MERLIN, we found that the high field phase is incommensurate spin density wave(SDW) with a multiple-q in the magnetic fields of 38-39 T. It shows the advantage of a white neutron Laue diffraction method to examine wide area of the reciprocal space, which is not possible in the ILL reactor experiment. Despite the important result obtained in the previous proposal, we need to continue the experiment to have the enough statistics to finalize the magnetic model of URu2Si2 and establish the understanding of QCP and hidden order.
