Description
Energy conversion effects are important in the design of efficient devices; they also involve a direct conversion between magnetic and mechanical energy – the so-called magnetoelasticity, which takes place in various applications such as force sensors, or magneto-acoustically driven low-energy demanding electronics. Mostly, the magnetoelasticity has been thoroughly studied in a high symmetry systems. Here, we focus on magnetoelastic behavior in a Pt-based system, which is able to
provide a stronger magnetoelastic response, focusing on the behavior of the ferromagnetic and antiferromagnetic systems represented, namely by FePt resp. MnPt.
Based on the ab-initio calculations, we discuss the relation of the magnetoelasticity and the magnetic ordering with the aim to make the link of the origin of electronic structure changes in the resulting magnetoelastic behavior. In addition, we discuss the modeling of the magnetoelastic behavior is such type of materials.
