Soft Magnetic Properties of the Fe76Si9B10P5/Zn0.5Ni0.5Fe2O4/PVA Composite Film

By Sheng Chen, Minggang Wang and Zhankui Zhao


Abstract. The Fe76Si9B10P5/Zn0.5Ni0.5Fe2O4/PVA composite film was fabricated by the spin-coating process. To improve the dispersibility and compatibility of Zn0.5Ni0.5Fe2O4 nanopaticles, Bis (P, P-bis-ethylhexyl diphosphato) ethanediolato titanate was used as the surface modifier to deal with Zn0.5Ni0.5Fe2O4 nanoparticles. The micro morphology and magnetic properties of the composites was observed respectively by 3D Measuring Laser Microscope OLS4000 and MATS type auto test system of magnetic materials. Several contrast groups using by the similar preparation process showed that surface modification on the Zn0.5Ni0.5Fe2O4 nanoparticles did not only improve the dispersibility of Fe76Si9B10P5 amorphous alloy particles presenting in the PVA, but also improve the softmagnetic properties of the composite films; the magnetic properties of the composite film containing Zn0.5Ni0.5Fe2O4 nanoparticles performed better than the one that not contain Zn0.5Ni0.5Fe2O4 nanoparticles; the permeability of the film increased with the increasing of the contents of Fe76Si9B10P5 amorphous alloy powder in the composites
