Analysis of magnetoelastic behavior in MnPt compounds using finite displacement method, suggesting improvements for magnetic materials.
Magnetic materials play an important role in the industry. Except for common material parameters such as magnetocrystalline anisotropy, magnetoelastic behavior can be significant for application serving in various devices, e.g. in acoustic actuators, transducers, or sensors providing desirable fast response and high efficiency. Magnetoelasticit properties have been studied for the cubic system. However, their magnetoelastic behavior is weak. Therefore, we focus on Pt-based tetragonal binary compounds bearing engaging magnetic behavior. We evaluate MnPt magnetoelastic behavior using the finite displacement method, discussing the influence of the magnetic structure, and focusing on the origin. While, the theoretically obtained results are compared to our performed experiments.
