摘要：This paper discusses magnetic characteristic of Ni-Fe permalloy thin film produced by electro deposited as flat core flux gate sensor. Ni-Fe thin films were deposited on printed circuit board (PCB) substrates with variation of composition in Ni percentage and current density J. In order to obtain high quality thin films, an additive ingredient of vanily was used to reduce rate deposition for whole experimental procedure. Experiment results showed that modified of magnetic characteristic evaluated by vibrating sample magnetometer was caused by the modified of deposition parameters. Coersive field (Hc ) increased with the increase of percentage of Ni composition, while the Hc did not form any particular pattern by modifying current density J. Finally, maximum saturated magnetization mS = 0.72 emu/gr was attained for percentage Ni of 51% and mS = 0.43 emu/gr for J = 5 mA/cm2 . Clarification by using STM showed that this was caused by the change of microscopic structure in Ni-Fe thin films.
