Antiferromagnetic resonance in $\alpha$-Fe${}_2$O${}_3$ up to its Néel temperature

Abstract

Hematite ($\alpha$-Fe${}_2$O${}_3$) 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.
