dcterms:description
In this paper we present a precise and cheap system we developed to measure BH loops of magnetic microwires. We especially focused on low frequency BH loops because we are mostly interested in quasi-static magnetic properties. Due to low frequency, we had to face problems related to low signal to noise ratio. The extremely small cross-section of the microwires turned out in very small flux to be measured. We achieved our goal by realizing a BH tracer based on induction principle, which generates the current necessary to create H field, and it synchronously samples the induced voltage. Digitized voltages are then sent to PC, which performs numerical analysis and returns the BH loop. The system has proved to be cheap and it provided excellent measurement parameters.
