FIRST STEPS WITH DIGITAL AC MAGNETOMETER

Tomáš Žák

   The setup of a computer driven digital AC magnetometer and their first tests are described. The magnetometer abilities are illustrated by measurements on closed and opened samples. The study of frequency influence is compared with DC measurement us-ing vibrating sample magnetometer. Though the results are satisfactory also without special magnetizing and pick-up coils, their construction is essential for the AC magnetometer enhancement and finalization.
