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

H. Lee, M. Yashima, M. Kakoi +7

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…

Fluctuation exchange study on the electron-hole asymmetry of the superconductivity across 1/3 filling in the trilayer Hubbard model

Yushi Yamada, Masataka Kakoi, Masayuki Ochi +1

We study within the fluctuation exchange approximation the trilayer Hubbard model where three layers of the Hubbard model are coupled by large interlayer hoppings so that the overl…

$t$ - $J$ model for strongly correlated two-orbital systems: Application to bilayer nickelate superconductors

Tatsuya Kaneko, Masataka Kakoi, Kazuhiko Kuroki

We derive a $t$ - $J$ model applicable to strongly correlated two-orbital systems including bilayer nickelate superconductors. Using the Schrieffer-Wolff transformation, we exclude t…

Microscopic evidence for spin-spinless stripe order with reduced Ni moments within $ab$ plane for bilayer nickelate La $_{3}$ Ni $_{2}$ O $_{7}$ probed by $^{139}$ La-NQR

Mitsuharu Yashima, Nina Seto, Yujiro Oshita +4

The intrinsic electronic properties of La $_{3}$ Ni $_{2}$ O $_{7}$ have been selectively investigated by nuclear quadrupole resonance (NQR) at the La(2) site outside the NiO $_{2}$ bilayers.…

Multiband Metallic Ground State in Multilayered Nickelates La $_{3}$ Ni $_{2}$ O $_{7}$ and La $_{4}$ Ni $_{3}$ O $_{10}$ Probed by $^{139}$ La-NMR at Ambient Pressure

Masataka Kakoi, Takashi Oi, Yujiro Ohshita +9

We report a $^{139}$ La-NMR study of polycrystalline samples of multi( $n$ )-layered nickelates, La $_{3}$ Ni $_{2}$ O $_{7 - δ}$ ( $n = 2$ ) and La $_{4}$ Ni $_{3}$ O $_{10 - δ}$ ( $n = 3$ ), at ambient pressure.…
