This work presents the results of the study of non-uniformly magnetized regions on the surface of thin magnetic films in multilayer magnetic tunnel junction (MTJ) structure Ta/CoFeB/MgO/CoFeB/Ta observed by highly sensitive magnetic force microscopy (MFM) probes. The micromagnetic simulation of the magnetization dynamics in CoFeB magnetic layer after the application of the external magnetic field of 0.5 T is conducted using mumax3 open-source software. The areas of the existence of magnetic vortices and domain walls in CoFeB magnetic film are found where the domain wall thickness was measured by MFM in the nanometer scale.
Keywords: magnetic force microscopy, thin magnetic films, magnetic domains, magnetic tunnel junction.
