Language eng - English Country US - United States Keywords inelastic neutron scattering ; exchange integrals ; RIXS spectra Subject RIV BM - Solid Matter Physics ; Magnetism CEZ AV0Z10100520 - FZU-D (2005-2011) UT WOS 000308736000014 DOI 10.1103/PhysRevLett.109.117207 Annotation From inelastic neutron scattering data we extract exchange integrals J1 and J2, both significantly larger than previous estimates. We establish that vicinity to criticality results in dramatic temperature dependence of Zhang-Rice singlet excitations.
