摘要：

The magnetic inductance of nanocrystalline Fe73Si16B7Nb3Cu1 and an amorphous FeSiB sheet has been investigated to identify the radiofrequency identification (RF1D) performance. Planar flow cast amorphous ribbons were pulverized and classified using a stack of sieve. The powder was mixed with binder and solvent and tape-casted to form 0.6-0.8 mm thick films. The inductance of the sheet was measured to investigate the RFID characteristics of the nanocrystalline and the amorphous materials. Results showed that the atmosphere for annealing significantly influenced on the inductance of the material. The surface oxidation of the particles was the main reason for the reduced inductance. The maximum inductance of Fe73Si16B7Nb3Cu1 alloy was about 88 mu H at 17.4 MHz, which was about 65% greater compared to the amorphous FeSiB alloy. The higher inductance in the nanocrystalline alloy indicates that it may be used as a potential replacement of current RFID materials.
