Acoustic emission, domain walls and hysteresis in YIG

The acoustic emission (AE) is experimentally shown to vary along the hysteresis loop of YIG samples with the creation and/or annihilation of domain walls. The AE and the Barkhausen activities are in anticorrelation. AE and hysteresis losses are proportional, which could mean that AE is the fundament...

Summary:The acoustic emission (AE) is experimentally shown to vary along the hysteresis loop of YIG samples with the creation and/or annihilation of domain walls. The AE and the Barkhausen activities are in anticorrelation. AE and hysteresis losses are proportional, which could mean that AE is the fundamental step to convert magnetic energy into heat.
