The defect structure of high-temperature superconductor La3Ni2O7

Abstract: La3Ni2O7 has attracted lots of attention recently as it hosts both high-temperature superconductivity under the application of hydrostatic pressure, and unusual magnetism with different density wave anomalies at ambient pressure. It is believed that oxygen vacancies, which seem to be intrinsic to the system, play a crucial role in the stability of these exciting phenomena. Whilst work has already identified that certain types of oxygen vacancies are more common that others, how these vacancies distort the surrounding crystal structure is less well known. Given that it is highly likely that these distortions will play an equally important role in understanding the exotic properties of La3Ni2O7, it is crucial to measure these effects. Here we propose to do just that by measuring the total scattering from powdered samples of La3Ni2O7 with different levels of oxygen deficiency.
