The magnetic shape memory alloy Fe70Pd30 is of particular interest for novel microactuator and sensor applications. Here we review the underlying physical and material science concepts by combining first principle calculations with combinatorial and epitaxial film studies. We address the following questions: What is the origin of the martensitic transformation? Can the addition of third elements improve the MSM properties? What is changing for epitaxial films and how can one obtain freestanding films?
