Orbital-Selective Coexistence of Interlayer Spin-Singlet Formation and SDW Order with Anomalous Spin Reconfiguration in Bilayer Nickelate La 3 Ni 2 O 7 Revealed by 17 O-NMR

The spin structure of the spin density wave (SDW) order in the bilayer nickelate La 3 Ni 2 O 7 has been investigated using site-selective 17 O-NMR measurements on the inner apical O(1), outer apical O(2), and planar O(3,4) sites. Below T SDW (= 150 K), the peak of all planar O(3,...
