Abstract
Different types of skyrmionics magnetic configurations can be created and manipulated on different types of nanostructures. In this research, we use micromagnetic simulations to study the dynamics of a skyrmionium on a racetrack in the presence of a semicircular magnetic defect. We considered a defect with physical parameters different from those of the racetrack itself. Our results show that, depending on the size of the defect, the width of the racetrack, and the intensity of the spin current density, it is possible to manipulate the trajectory of a skyrmionium. Also, we obtain the interaction energies between the skyrmionium and the magnetic defect and derive phase diagrams showing the different dynamic states that can be obtained during the movement of the skyrmionium.
