IEEE Transactions on Magnetics, 1972 A low temperature process for converting hematite (α-Fe 2 O 3 ) thin films into magnetite (Fe 3 O 4 is described. The films produced are unambiguously identified as magnetite by several complementary methods of analysis. These include α-backscattering spectrography, X-ray powder diffractometry, and observations of electrical, magnetic, and optical ...
