Abstract :
This study aims to demonstrate domain wall motion and magnetic charge carrier trajectory in artificial spin ice lattice with the aid of magnetic force microscopy imaging. The physics behind selective motion of domain wall is based on the conservation of topological edge defects and minimization of demagnetization energy. Results show that the asymmetry in magnetic network structure helps to control the path of the domain wall and lead to deterministic Dirac strings in artificial spin ice.
