The report presents the results of an experimental study on the observation of inhomogeneous magnetic distributions by the Lorentz electron microscopy method in Permalloy nanodisks and Co/Pt multilayer films. Magnetic nanodisk systems were used to calibrate the magnetic field in the objective lens of the microscope LIBRA 200MC. The magnetic properties of Co/Pt multilayer films were locally modified by irradiation with a sharply focused ion beam in a scanning helium ion microscope. As a result of such irradiation, periodic lattices of inhomogeneous magnetization distributions were formed in continuous films, the spin configuration of which depends on the dose of local irradiation.
