Here, using high resolution angle-resolved photoemission spectroscopy in a detailed temperature dependence study, we identify a clear response of the electronic structure to a dimensional crossover in the form of two distinct temperature scales marking onsets of modifications in the electronic structure. Specifically, we observe Te \U0001D45D-orbital-dominated bands to undergo changes at the Curie transition temperature \U0001D447\U0001D436 while the Cr \U0001D451-orbital-dominated bands begin evolving at a higher temperature scale. Combined with neutron scattering, density functional theory calculations, and Monte Carlo simulations, we find that the electronic system can be consistently understood to respond sequentially to the distinct temperatures at which in-plane and out-of-plane spin correlations exceed a characteristic length scale. Our findings reveal the sensitivity of the orbital-selective electronic structure for probing the dynamical evolution of local moment correlations in vdW insulating magnets." description_type: abstract lang: eng ## Creator - name: Han Wu role: author organization: Rice University - name: Jian-Xin Zhu role: author organization: Los Alamos National Laboratory - name: Lebing Chen role: author organization: University of California at Berkeley - name: Matthew W.
