“…By temperature-dependent x-ray diffraction we can exclude this, which illustrates the need to combine independent methods to probe these multifunctional materials. In these experiments, the reentrant transformation is probably hindered by the low film thickness since the rigid substrate conditions often hinder transformation [ 28 , 29 ] and affect the magnetism [ 30 ]. Nevertheless, our work is the first to obtain epitaxial films as model systems to open up the exploration of RMT in thin films.…”

During cooling, conventional martensitic transformation can only be realized from austenite to martensite. Recently, a so-called reentrant martensitic transformation attracted much interest due to an additional transformation from martensite to austenite during further cooling. Obviously, materials with this reentrant transformation will increase the number of physical effects and possible applications. However, until now, only bulk samples have been available, which are not suitable for applications in micro-devices. In this work, we focus on the Co-Cr-Ga-Si system and examine the suitability of this system for the growth of thin films. We observed that the films grow epitaxially on MgO (100) substrates and exhibit a martensitic transformation if deposited at a sufficiently high temperature or with an additional heat treatment. Films within the austenite state are ferromagnetic while films within the martensitic state just exhibit a very low ferromagnetic order.

“…These advances are very promising and can be extended to other systems already studied in nanomagnetism on rigid substrates. First of all, GMI sensors come to mind [56,105,106,[171][172][173], of which a few groups have become specialists [55,174]. These have shown that these systems are already very good candidates for the applications such as MI-based sensor devices.…”

This paper provides a topical review of work on systems based on magnetic nanostructured thin films on polymer substrates. This topic has indeed experienced a significant growth in the last ten years. Several studies show a strong potential of these systems for a number of applications requiring functionalities on non-planar surfaces. However, the deformations necessary for this type of applications are likely to modify their magnetic properties, and the relationships between strain fields, potential damages and functional properties must be well understood. This review focuses both on the development of techniques dedicated to this research, on the synthesis of the experimental results obtained over the last ten years and on the perspectives related to stretchable or flexible magnetoelectric systems. In particular, the article focuses on the links between magnetic behavior and the strain field developing during the whole history of these systems (elaboration, reversible and irreversible loading).
