Abstract

Hematite ( α-Fe2O3) is an antiferromagnetic material with a very low spin damping and high Néel temperature. The temperature dependence of the antiferromagnetic resonance in a bulk single crystal of hematite was characterized from room temperature up to the Néel temperature in the frequency range of 0.19–0.5 THz. From these data, the Néel temperature was estimated as 966 K.
