Solid-State Dewetting as a Driving Force for Structural Transformation and Magnetization Reversal Mechanism in FePd Thin Films

In this work, the process of solid-state dewetting in FePd thin films and its influence on structural transformation and magnetic properties is presented. The morphology, structure and magnetic properties of the FePd system subjected to annealing at 600 degrees C for different times were studied. The analysis showed a strong correlation between the dewetting process and various physical phenomena. In particular, the transition between the A1 phase and L1(0) phase is strongly influenced by and inextricably connected with solid-state dewetting. Major changes were observed when the film lost its continuity, including a fast growth of the L1(0) phase, changes in the magnetization reversal behavior or the induction of magnetic spring-like behavior.

Automated summary

This work presents the process of solid-state dewetting in FePd thin films and its impact on structural transformation and magnetic properties. The morphology, structure, and magnetic properties of the FePd system after annealing at 600 degrees C for different durations were investigated. The analysis revealed a strong correlation between the dewetting process and various physical phenomena, particularly the transition between the A1 phase and L1(0) phase, which is strongly influenced by and connected with solid-state dewetting.
