Ferromagnetic Shape Memory Alloys
Description:
Multiferroic shape-memory alloys that exhibit both ferroelastic and ferromagnetic properties have recently attracted much attention. They belong to the family of so-called “smart materials” and are future-generation materials that are likely to be useful in cutting-edge technologies. Apart from the theoretical challenge of understanding their fascinating properties, the quest to harness them for practical use is also attracting many scientists and engineers from all over the world.

Review from Ringgold Inc., ProtoView:
Unique among shape memory alloys (materials that can return to their original configuration after being deformed), are ferromagnetic shape memory alloys that change shape under strong magnetic fields. These 27 papers comprise the proceedings of a November 2007 conference that focused on engineering ferromagnetic shape memory alloys that are more versatile and commercially viable. Subjects include sample preparation for experimentation, thermal treatments and phase stability, magnetic and structural characterization, alloys suitable for applications at the micro scale, resistance and magnetocaloric effects, with papers covering physical phenomena in magnetic shape memory science, main patterns in NiMnGa films, ferromagnetic materials in silicon wafers, transformations in NiMnGa alloys, acoustic energy absorption, shape memory alloys in polymer composites, hybridization effects, and properties of Heusler alloys.
