(a) Normalized magnetization \(M/{M}_{S}\) curves as a function of temperature and (b) its temperature derivative curves with the indication on the M-phase transition region and the O(I)-phase Curie temperature. Magnetization isotherms curves for (c) 2 wt.%, (d) 12 wt.% PVDF/GSG composites and (e) for the powder.
