Evolution of magnetism in Ruddlesden-Popper bilayer nickelate revealed by muon spin relaxation

K. W. Chen, X. Q. Liu, Y. Wang +5

Here we report the positive muon spin relaxation study on Pr-doped La${}_{1.9}$Pr${}_{1.1}$Ni${}_2$O${}_{6.97}$ and oxygen-deficient La${}_3$Ni${}_2$O${}_{6.63}$ polycrystalline under ambient pr…
