Abstract The goal of this work is to determine how the rate Ni deposition rates affect structural characteristics that regulate magnetization Ni/Al multilayer thin films sputtered on flexible acrylic acetate polymer substrates. with a 5[Ni(20 nm)/Al(10 nm)] structure were gradually as different in total thickness 150 nm. With an increase deposition, contents increased from 61.5% 69.6%. And, X-ray diffraction analysis verified featured face-centered cubic variable peak intensities. Also, scanning electron microscopy surface morphology analyses revealed variations film surfaces result rates. For magnetic measurements, differences observed cause notable variation saturation magnetization, M S , and coercivity, H C values. Accordingly, values consistently between 359.0 389.7 emu cm −3 but decreased around 34–32 28 Oe 0.02 0.10 nm s −1 . It also when layers are generated at very fast rates, have high /H ratio, which significant for sensors. has been concluded magnetisation can be controlled by properties adjusting rate.
