MSCA4Ukraine fellowship proposed by Ganna Kharchenko under supervision of Michal Urbanek. This project introduces an innovative approach to create artificial skyrmionic crystals by stabilizing skyrmions in low-damping, soft ferromagnetic media at room temperature, without DMI and the need for external magnetic fields. I aim to stabilize interacting skyrmion arrays utilizing dipolar interactions in an in-plane continuous ferromagnetic film coupled with an antidot matrix patterned into perpendicularly magnetized hard magnetic layer. The interacting skyrmion array can be then used as a magnonic crystal to control the spin wave propagation and at the same time the spin waves can be used to reconfigure the individual skyrmions inside the crystal. The project will primarily focus on exploring the outlined ideas using micromagnetic simulations, however the most promising results are planned to be tested also experimentally using applicant’s host group nanofabrication facilities and their experience with characterization of dynamics of nanomagnetic systems. This could pave towards advanced skyrmion-based technologies, offering building blocks for next-generation of energy-saving spintronic devices.
