Abstract
An experimental setup which simultaneously registers induced Barkhausen pulses and short time variations in electrical resistance has been developed. The skin effect associated with the use of an alternating current of 100 kHz reduces the volume of the sample which is sensitive to the passing of the current, making it possible to detect the rapid modifications in resistance in a standard Ni thermocouple wire subjected to a slowly varying magnetic field. The combination of both techniques clearly shows the association between jumps in resistance and the dynamics of some magnetic domains.
