(a) The M-H hysteresis loops measured under H_FC = 0.2 kOe and 50 kOe at T = 2 K for a Fe₁₁Au₈₉(50 nm)/FeNi(5 nm) sample, (b) the calculated M-H hysteresis loops under H_FC = 0.2 kOe and 50 kOe at T = 2.6 K for the SG/FM bilayers, and the experimental (c) and calculated (d) cooling field dependences of low-temperature H_E and H_C.
