  1. The previously documented largest SANE in AFMs is ~6 μV K−1 in the same compound as this work but in a different configuration. The other referenced compounds in the table are FMs, among which UCo0.8Ru0.2Al established the apex SANE value of ~23 μV K−1. Even though for sample 1 of this study, we cannot reliably separate the ANE from the total Nernst thermopower, the tendency of values of Syx above 180 K is to saturate above 70 μV K−1; therefore, the findings of the present research may well set a new world record for ANE thermopower in magnetic materials.
