Temperature-dependent infrared optical spectra of La4Ni3O10

This dataset contains temperature-dependent polarization-resolved infrared spectroscopy data for single-crystal La4Ni3O10, associated with the paper “Electronic layer decoupling driven by density-wave order in La4Ni3O10”. The dataset includes measured reflectivity spectra and Kramers–Kronig-derived optical constants for two light polarizations: E || ab and E || c*. For each temperature and polarization, the data files include frequency, reflectivity, the real and imaginary parts of the optical conductivity, the complex refractive index, and the complex dielectric function. The dataset does not include fitting results, density-functional-theory calculations, or other derived modeling outputs.
