Field dependences of MEP in SMO after the elimination of the time-dependent contribution. Curves 1–5 are measured in the field along the [010] axis; curves 6–10 are measured in the field along the [100] axis. The temperatures: curves (1, 6) T = 4.4 K; (2, 7) 2.6 K; (3, 8) 1.4 K; (4, 9) 0.9 K; (5, 10) 0.43K.
