heal.abstract	In this paper a new magnetostrictive delay line set-up for sensor applications is proposed. The tri-layer set-up consists of an inner cylindrical copper core. an intermediate thin insulating layer and an outer circumferential magnetoelastic thin film. Packaging reasons require a coating-insulating layer on top of the set-up. Different Fe-Ni compositions have been tested for the magnetostrictive film. Characterization of the devices showed that negative magnetostrictive film operates as a magnetostrictive delay line set-up, even without magnetic and heat treatment. Concerning positive magnetostrictive films. heat treatment was necessary to allow the propagation and detection of the elastic pulses. (c) 2005 Elsevier B.V. All rights reserved.	en
