Abstract

The bilayer nickelate superconductor La₃Ni₂O₇undergoes a density wave transition near 150 K that has attracted intensive scrutiny, yet its microscopic origin remains elusive. Here we report polarization-resolved electronic Raman scattering measurements on high-quality single crystals of La₃Ni₂O₇. Below 150 K, we observe a pronounced, symmetry-dependent redistribution of spectral weight in B_1gand B_2gchannels, consistent with the formation of spin-density-wave (SDW) gaps. Quantitative analysis reveals momentum-selective SDW gap amplitudes, with intermediate-to-strong coupling near X/Y points of the Brillouin zone and weaker coupling along the diagonal direction, indicating an unconventional SDW driven by anisotropic electronic correlations. Our results establish the electronic character of the SDW in La₃Ni₂O₇, and provide a microscopic foundation for understanding the emergence of high-temperature superconductivity under pressure in nickelates.
