Abstract

This data package contains the terms of a quantum Heisenberg model for the antiferromagnet hematite, specifically small clusters with periodic boundary conditions. It also contains magnetisation curves and spin-flop fields extracted from that model by means of exact diagonalisation (ED) and density-matrix renormalisation group (DMRG) theory, as well as mean-field (MF) and spin-wave (SW) theory.
