Local thermal magnetization fluctuations in Li-doped MnTe are found to increase its thermopower α strongly at temperatures up to 900 K. Below the Néel temperature (<i>T</i> <sub>N</sub> ~ 307 K), MnTe is antiferromagnetic, and magnon drag contributes α<sub>md</sub> to the thermopower, which scales as ~<i>T</i> <sup>3</sup>. Magnon drag persists into the paramagnetic state up to >3 × <i>T</i> <sub>N</sub> because of long-lived, short-range antiferromagnet-like fluctuations (paramagnons) shown by ...[more]
