Fig. 1. (a-c) ZFC/FC magnetization as a function of temperature in the low temperature range at selected JSG under H = 200 Oe, and the complete curves in the studied temperature range are also shown in insets. (d) FM TC, SG Tg, TMAXZFC and superparamagnetic blocking <TB> in SG/FM bilayer as a function of JSG.
Fig. 2. (a) Magnetization as a function of time at T = 10 K after field cooling under H = 2 kOe at selected JSG. (b) M0 and (c) β obtained through fitting Eq. (2) in the text as a function of JSG.
Fig. 3. Hysteresis loops at T = 10 K after field cooling under H = 200 Oe in (a) undoped and (b) doped SG/FM bilayer with selected JSG, where arrows indicate the movement of the curves at descending and ascending branches with JSG. (c) HE and (d) HC as a function of JSG in SG/FM or AFM/FM bilayer, and vertical dashed line is used to indicate a clear boundary between two JSG ranges where pronounced HE (at small JSG) and reduced HC (at large JSG) in SG/FM bilayer are observed, respectively.
Fig. 4. (a) Mnet@IF as a function of JSG in undoped and doped SG/FM bilayer. Insets show magnetic structures of SG@IF at selected JSG, where red (grey in black/white print) and blue (dark grey in black/white print) spheres represent SG spins pointing closely parallel and antiparallel to +x axis, respectively, and orange (light grey in black/white print) area indicates FM-like domains. SRI as a function of H in (b) undoped and (c) doped SG/FM bilayer with JSG = 4.55 and 5.85 erg/cm2.
