Description
Magnetic materials represent a key component in the industry. One of the most common and used magnetic material parameters is magneto-crystalline anisotropy, which takes place in permanent magnets, storage devices, etc. In addition, magnetoelastic behavior is widely used in many applications, such as acoustic actuators, transducers, or sensors, providing desirable fast response and high efficiency. The study of this phenomenon is substantial and engaging from the point of view of material design.
Since magnetoelastic behavior of cubic transition metallic systems is weak, we are focusing on the Pt-based tetragonal system studying from first principles the impact of the magnetic ordered structure on the magnetoelastic coefficients. We show a substantial effect on the magnetoelastic properties including the volume and anisotropic magnetostriction depending on the assumed magnetic structure.
The obtained calculated results are used to explained experimentally measured magnetoelasic behavior.
