Magnetic and transport studies on nanocrystalline Fe73.5Si13.5B8CuNb2VAl ribbon

The magnetic and the transport properties of the Fe73.5Si13.5B8CuNb2VAl nanocrystalline ribbon have been presented. The coercive field was found to increase from 0.24 to 1 Oe on lowering the temperature from 300 to 5 K. The irreversibility in the FC–ZFC was observed and the magnetization was found to follow T3/2 law. Magnetoresistance measurements were done along the length of the ribbon and the MR of −0.07% was observed at 300 K. Cluster glass behavior was predicted by the power law.
