Thermal behaviors of $(Cu_{0.5}Mn_{0.5})Fe_2O_4$, prepared by a solid method, were investigated for $H_2$ production by a thermochemical cycle. The thermal reduction of $(Cu_{0.5}Mn_{0.5})Fe_2O_4$ started from $300^\circ{C}$ and the weight loss was 1.3 wt% up to 1200. XRD shows the prepared ferrite has the spinel structure with a lattice constant of $8.414{\AA}$ and changed to the oxygen deficient structure by thermal reduction. Oxygen and hydrogen can be separately produced by the cycles of thermal reduction and water oxidation of the oxygen deficient ferrite.
