We present the results of the effect of annealing in hydrogen atmosphere on the magnetic properties of continuous magnetic films and patterned structures. Rectangular and elliptical particles, with lateral dimensions in the range 150–900 nm, were made of 24 and 66 nm thick permalloy films. The domain structure and the magnetization reversal processes were investigated by magnetic force microscopy and alternating gradient magnetometry. While the performed annealing at 200 °C during 48 h did not noticeably change the properties of the continuous films, it influenced the patterned structures significantly. The difference between patterned elements and the continuous films can be explained by enhanced relaxation and vacancy diffusion in the particles
