Preparation of Ni-Mn-Zn Ferrite Films on CeO2/YSZ-Buffered Si Substrate

Article Preview

Abstract:

Ni-Mn-Zn ferrite films were deposited on Si substrate with CeO2/YSZ(YSZ:yttria-stabilized ZrO2) buffer layer by pulsed laser deposition (PLD). The effect of CeO2/YSZ buffer layer on the Ni-Mn-Zn ferrite film was studied by XRD, SEM and VSM. The results revealed that the CeO2/YSZ buffer layer can improve the films crystallinity, smooth the roughness of film, reduce the film crack and lead to a homogeneous microstructure. The saturation magnetization (Ms) higher than 240 emu/cm3 can be obtained. It also found annealing process can improve the film crystallinity and the magnetic properties, decrease the coercivity (Hc).
