In our research, we employ a protocol, dubbed entanglement microscopy, to reveal the multipartite entanglement encoded in the full reduced density matrix (RDM) of microscopic subregion in spin and fermionic many-body systems. Raw data for Ising reduced density matrices generated by the quantum Monte Carlo algorithm at 1D and 2D is provided here. RDMs with 2-site, 3-site, and 4-site subregions are included in folders with corresponding names. Folders with the suffix "_beta" contain RDMs at finite temperatures.
