Inverted Hysteresis Loops in the Fe73.5Cu1Nb3Si13.5B9 Alloy With Small Coercivity

The phenomenon of inverted hysteresis loop has been observed in many materials for the past decades. However, the physical origin of the inverted hysteresis loop has long been debated. Here, we report the completely inverted hysteresis loop with a clockwise cycle in the soft-magnetic nanocrystalline Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 alloy and amorphous Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 alloy at room temperature. The negative remanence and positive...
