Magnetic field induced shape memory effect of Fe-Pd alloy thin film.

Understanding the Magnetic Shape Memory System Fe – Pd – X by Thin Film Experiments and First Principle Calculations

The magnetic shape memory (MSM) alloy Fe70Pd30 is of particular interest for novel microactuator and sensor applications. This review summarizes the underlying physical and material science concepts for this MSM alloy system. First-principles calculations of the electronic and crystallographic structure together with combinatorial and epitaxial film studies are presented. By these complementary...

Thin film shape memory alloys and microactuators

For Micro-electro-mechanical System (MEMS) applications, TiNi-based thin film Shape Memory Alloys (SMAs) possess many desirable properties, such as high power density, large transformation stress and strain upon heating and cooling, superelasticity and biocompatibility. In this paper, recent development in TiNi-based thin film SMA and microactuator Thin film SMAs and microactuators 209 applicat...

Magnetic-Field Induced Strains in Ferromagnetic Shape Memory Alloy Ni55Mn23Ga22 Deposited by RF-Magnetron Sputtering

1.5mm–Ni55Mn23Ga22 ferromagnetic thin films were deposited onto silicon substrates and silicon single beam cantilever using radio-frequency magnetron sputtering. As-deposited sample and heat-treated thin films were studied on their silicon substrates and peeled off to determine the influence of the stress. Post-heat treatment process allows at the films to achieve the shape memory effect (SME)....
