WebVSM analysis showed that the composite has good magnetic properties. Atomic force microscopy recorded a surface roughness of the composite of about (125 nm) while the average thickness was approximately (10.3 nm). Significant responses of the capacitance–voltage profiles in the employed Preisach model, have been also recorded. Webterials based on Preisach theory, requires a Preisach distribution function characterising the material. Although it is possible to ob-tain all the data for a classical Preisach model from experimental first-order curves, obtaining the Preisach distribution function by differentiating this data twice leads to large errors and even to
