AC HYSTERESIS LOOP TRACER FOR SOFT MAGNETIC THIN FILMS

Luděk Kraus – Oleksandr Chayka

   A high sensitive inductive AC hysteresis loop tracer for the measurements of thin films with the thickness down to few nm is described. The equipment is build entirely with commercially available instruments. The sensitivity is substantially increased by improving the signal-to-noise ratio by means of data acquisition and processing using a digital storage oscilloscope.
