Abstract Ferromagnetic resonance is observed in the 1.25 cm microwave band in polycrystalline hematite samples after subjecting them to high‐temperature pulses in air. The intensity and width of the resonance line are found to depend on the duration of the horizontal part of the pulse and on the cooling rate. This ferromagnetic resonance absorption is shown to be related with the formation of a ferromagnetic phase structurally identic with magnetite.
