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.…
