ABSTRACT
Spinel NiZn ferrite thin films were performed on polycarbonate glass substrates by spray deposited method at low temperature (<90 °C). After addition of cetyltrimethylammonium chloride(CTAC) made the adsorptive energy of substrate surface increase, smooth surface and uniform columnar film structures were obtained. The optimum reaction temperature up to 85 °C and the solution pH up to 7.5 were obtained. When the pH solution value increases from 6.5 to 7.5, the saturation magnetization accordingly increases to 2.48 × 105 A/m and resistivity to 5.6 × 102 Ω cm. The high real permeability (μ′) of 36.1 and magnetic loss (μ″) of 53.2 for the ferrite film at 500 MHz were achieved. As the ferrite plate thickness is 1 mm, the attenuating characteristics for reflection loss ≤−10 dB can be obtained in the wide range between 0.5 GHz and 2.7 GHz.
