Magnetic and transport studies on nanocrystalline Fe <inf>73.5</inf>Si <inf>13.5</inf>B <inf>8</inf>CuNb <inf>2</inf>VAl ribbon

The magnetic and the transport properties of the Fe 73.5Si 13.5B 8CuNb 2VAl 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 FCZFC was observed and the magnetization was found to follow T 3/2 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. © 2011 Elsevier B.V.
