Amorphous magnetostrictive thin films for sensor applications — •Eckhard Quandt — Lehrstuhl für Anorganische Funktionsmaterialien, Institut für Materialwissenschaft, Technische Fakultät, Christian-Albrechts-Universität zu Kiel, Kaiserstr. 2, 24143 Kiel

Magnetron sputtered amorphous FeCoBSi thin films are attractive for different sensor applications due to their softmagnetic properties, their high piezomagnetic coefficient and their good high frequency properties.

The presentation describes mainly the dependency of the magnetic properties of FeCoBSi films on strain. Vibration sample magnetometer (VSM), Kerr-effect, magneto-optical indicator film (MOIF) techniques, and high frequency permeameter measurement data obtained with special test jigs are discussed in view of applications as remote interrogated stress sensors or as multiferroic magnetic field sensor.
