Elastic neutron scattering study on the magnetic structure of the double layer nickelate La3Ni2O7

Abstract: The spin degree of freedom plays a critical role in the newly discovered bilayer nickelate superconductor with Tc around 80 K under moderate pressure. Various experiments, including RIXS, ?SR, and NMR, have con?rmed the presence of a spin-density-wave order below 150 K at ambient pressure. However, the magnetic structure remains unsolved. Here we propose an elastic neutron scattering experiment on high quality La3Ni2O7 single crystals. By measuring magnetic Bragg peaks at low temperatures?analyzing their positions in reciprocal space and intensities?and conducting magnetic structure re?nement simulations, we aim to precisely determine the magnetic structure of La3Ni2O7, ultimately advancing our understanding of the mechanism behind its high-temperature superconductivity within this framework.
