a, Comparison of the absolute values of |αANE|/M, |SANE|/M and M of YbMnBi2 in the bc configuration (160 K) with those of other compounds with large ANE thermopowers—namely, the ferromagnets Fe3Ga (300 K)2, Co2MnGa (300 K)3,9, Co3Sn2S2 (80 K)7, UCo0.8Ru0.2Al (40 K)15, MnBi (80 K)37, Ga1−xMnxAs (10 K)42, and the chiral antiferromagnets Mn3Sn (300 K)6,12 and Mn3Ge (300 K)10,32. Antiferromagnets are marked as AFM, and other materials are all ferromagnets. b, The temperature dependence of zTANE values for YbMnBi2 in the bc configuration compared with those of other compounds with large ANE thermopowers.
