Abstract

Hematite ( $\alpha$ -Fe $_2$ O $_3$ ) is an antiferromagnetic material with a very low spin damping and high N\'eel temperature. The temperature dependence of the antiferromagnetic resonance in a bulk single crystal of hematite was characterized from room temperature up to the N\'eel temperature in the frequency range of 0.19-0.5 THz. From these data, the N\'eel temperature was estimated as 966 K.
