Abstract

A study of the magnetic Barkhausen effect emissions in 2605 CO amorphous alloys has been made. These emissions, which appear as magnetization pulses in the material, can be detected by a pick-up coil and analyzed in a variety of ways. In this study the Barkhausen effect signals were found to be dependent on both magnetic field and applied tensile stress. This dependence was in accordance with a theoretical model of the Barkhausen effect developed previously. The analysis and modeling of the resulting behaviour was found to be particularly simple because amorphous alloys have no crystalline anisotropy, and therefore the effects of stress on the Barkhausen emissions were not masked by competing effects
