Characterization of Ni2MnGa Single Crystal for Sensor Applications — •Christoph Bechtold1, Andreas Gerber1, and Eckhard Quandt1,21Stiftung caesar, AG Smart Materials, Ludwig-Erhard-Allee 2, 53175 Bonn — 2CAU Kiel, Technische Fakultät, Inst. f.

In the past 10 years MSM materials received attention as actuator materials on account of their large magnetically induced strains. Sensor applications were almost not pursued. However, those are very attractive and are the focus of this work. The corresponding sensor approaches are the use of MSM/polymer composites as mechanical sensors or as magnetic field sensors by employing piezoelectric polymers.

In this presentation the properties of Ni2MnGa single crystals were characterized with respect to features important for these sensor applications. Especially strain versus pre-stress and change of permeability as a function of strain were measured and will be discussed in view of the envisaged applications.
