چکیده انگلیسی
Structure and magnetization of CoZrNb amorphous films prepared by DC magnetron sputtering have been studied as a function of film thickness (t), from 35 to 840Â nm. Using comprehensive characterization, we show that the CoZrNb amorphous films possess a single phase and no nanocrystalline can be detected. The magnetic measurements indicate that the magnetization reversal of CoZrNb films is strongly dependent on t. That is, the coercivity is abruptly reduced to be lower than 4Â Oe with t increasing from 35 to 105Â nm, and then gradually decreases to â¼0.2Â Oe as t increases. This coercivity transition versus t is accompanied by the strong magnetization reversal when t is larger than 105Â nm. The results reveal that CoZrNb amorphous films with comparatively large film thickness (>100Â nm) are suitable for sensors and anti-faked materials.
