Defect modeling in skyrmionic ferromagnetic systems

Defects are unavoidable in real materials. Defects, either intrinsic or artificially incorporated, can alter the material properties. In the particular case of skyrmionic ferromagnetic materials, defects modify the stability and dynamics of the skyrmions. These magnetic structures have aroused great interest due to their potential as information carriers. Hence, the knowledge and control of the influence of defects on skyrmions are essential for their use in applications, such as magnetic memories or information mobility. Aiming to give an overview on defect simulations, we review the most relevant approaches to simulate defects in ferromagnetic materials, hosting skyrmions depending on their size, nature, strength, and quantity.
