Figure 1:  Simulated initial hysteresis curves for (a) varying nanocrystal size (lnc) with constant volume fraction (φnc) = 0.3; (b) varying volume fraction (φnc) with constant (lnc) = 20 nm; (c) micromagnetic models for specific case volume fraction (φnc) of 0.3 and nanocrystal size (lnc) of 20 nm at specific magnetic fields (Hext) at  (c1) 0.0 T, (c2) 0.8 T, (c3) 5.0 T, (c4) 6.5 T and (c5) 8.0 T(Ms is valued as the maximum magnetization of each hysteresis).
