Magnetoelastic behavior calculations in tetragonal systems — •Jakub Sebesta and Dominik Legut — IT4Innovations, VSB-TU Ostrava, 17.listopadu 2172/15, 708 00 Ostrava-Poruba, Czech Republic

In modern devices, various energy conversion effects are used for efficient operation. One of these effects represents magnetoelasticity – the conversion between the magnetic and mechanical energy. It is widely used in sensors or actuators e.g. force or torque sensors, fuel injectors, micro-pump, etc. So far, high symmetry systems, such as ferromagnetic 3d elements or rare-earth-based Laves phases, have been studied especially. In contrast ,here we provide a theoretical investigation of magnetoelastic behavior in tetragonal systems, focusing on the determination of the magnetoelastic properties influenced by the magnetic structure, and investigating the source of the observed modification. Eventually, we discussed a simple theoretical model for the magnetoelasticity in the considered systems.
