Mechanism for the occurrence of ZTE. NTEM and PTET denote negative thermal expansion caused by magnetic ordering and positive thermal expansion caused by temperature, respectively, and aM and aT are the corresponding lattice parameters. ΔaM and ΔaT are the changes in the lattice parameter caused by magnetic ordering and temperature, respectively. In the temperature range…
