Is it possible to convert hematite Fe2O3 into magnetite Fe3O4 with annealing (~1000 C) without using reducers?

I know you can reduce Fe2O3 to Fe3O4 with controlled reducing at 1000 C with methane. Now, without reducers, I heat MgFexOy (which is not magnetic and nano-sized particles) at 1000 C for 6 hours...
