  Recent developments in the magnetization dynamics in spin textures,
particularly skyrmions, offer promising new directions for magnetic storage
technologies and spintronics. Skyrmions, characterized by their topological
protection and efficient mobility at low current density, are increasingly
recognized for their potential applications in next-generation logic and memory
devices. This study investigates the dynamics of skyrmion magnetization,
focusing on the manipulation of their topological states as a basis for bitwise
data storage through a modified Landau-Lifshitz-Gilbert equation (LLG). We
introduce spin-polarized electrons from a topological ferromagnet that induce
an electric dipole moment that interacts with the electric gauge field within
the skyrmion domain. This interaction creates an effective magnetic field that
results in a torque that can dynamically change the topological state of the
skyrmion. In particular, we show that these torques can selectively destroy and
create skyrmions, effectively writing and erasing bits, highlighting the
potential of using controlled electron injection for robust and scalable
skyrmion-based data storage solutions.
