Magnetization Dynamics along a Magnetic Nanowire under a Localized Thermal Gradient.

The magnetization dynamics along a magnetic nanowire under a localized thermal gradient is investigated using the framework of the stochastic Landau-Lifshitz-Gilbert equation. Thermally induced Domain Wall displacement is compared in various cases. The laser width can affect the displacement of the DW inside a nanowire, which is shown here. Also, the distance between DW and laser width can influence DW movement which is compared in this study. These findings highlight the importance of optimizing thermal gradient parameters (e.g. spatial extent and proximity to the DW) for reliable control of DW motion in spintronics applications. The study also provides insights into the design of low-energy, thermally driven nanodevices, such as racetrack memories or logic gates, where precise DW manipulation is critical. Future work could explore temperature- dependent material properties, alternative nanostructures, and experimental validation to bridge theoretical predictions with practical implementations.
