We studied vortex nucleation/annihilation process and its temperature dependence in micromagnetic objects with lowered symmetry using micro-Hall magnetometry. Magnetization reversal curves were obtained for the Pacman-like nanodots placed directly on

Future spintronic devices based on skyrmions will require precise control of the skyrmion motion. We show that this goal can be achieved through the use of magnetic antidot arrays. With micromagnetic simulations and semi-analytical calculations based

In this work, we present the influence of the curvature of magnetic nanodot on the vortex gyrotropic mode frequency. We show that gyrotropic oscillation of the magnetic vortices is highly influenced by the rounding of the nanodot shape due to the for

We have developed a vortex-core magnetic force microscope (VC MFM) for magnetic field imaging at the nanoscale for many research fields—physics, biology, materials science, and metrology. The method solves principally quantitative scanning by incre

Knowledge of free energy barriers separating different states is critically important for assessment of long-term stability of information stored in magnetic devices. This information, however, is not directly accessible by standard simulations of mi

In this work we present two fabrication approaches for patterning submicron Pacman-like (PL) magnetic nanoelements, the additive and subtractive process. Within the first process, PL structures are revealed using a standard lift-off technique. The se

In this paper we explore magnetic properties of Permalloy Pacman-like (PL) nanomagnets in external in-plain magnetic field. PL nanomagnets represent unique magnetic systems with broken symmetry, which are perspective as non-volatile memory elements.
