Notes:
The magnetic inductance of nanocrystalline Fe73Si16B7Nb3Cu1 and an amorphousFeSiB sheet has been investigated to identify the radiofrequency identification (RFID)performance. Planar flow cast amorphous ribbons were pulverized and classified using a stack ofsieve. The powder was mixed with binder and solvent and tape-casted to form 0.6-0.8 mm thickfilms. The inductance of the sheet was measured to investigate the RFID characteristics of thenanocrystalline and the amorphous materials. Results showed that the atmosphere for annealingsignificantly influenced on the inductance of the material. The surface oxidation of the particleswas the main reason for the reduced inductance. The maximum inductance of Fe73Si16B7Nb3Cu1alloy was about 88μH at 17.4 MHz, which was about 65% greater compared to the amorphousFeSiB alloy. The higher inductance in the nanocrystalline alloy indicates that it may be used as apotential replacement of current RFID materials
