Language eng - English Country US - United States Keywords RIXS ; spin correlations ; temperature dependence of Zhang-Rice singlet Subject RIV BM - Solid Matter Physics ; Magnetism Institutional support FZU-D - RVO:68378271 UT WOS 000315141600030 DOI 10.1103/PhysRevLett.110.087403 Annotation Comparing the experimental data to many-body calculations we have identified the strong excitation around 3.5 eV as Zhang-Rice singlet excitation on neighbouring CuO4 plaquettes. The strong temperature dependence of this excitation enables us to probe short-range spin correlations on the 1 meV scale with outstanding sensitivity.
