Remagnetization kinetics of the bilayer ferromagnetic/superconductor (FeNi/Nb) and ferromagnetic/antiferromagnetic (FeNi/FeMn) ultra-thin films is investigated. Experimental results are obtained by direct observation of domain structure using the magneto-optic visualization technique in a wide temperature range. It is found that proximity of a second layer varies drastically the FeNi magnetic properties, such as domain and domain boundary structures, domain boundary mobility, coercivity. Moreover, the mechanism of magnetization is found to be temperature dependent. The effect of temperature becomes especially pronounced below 50 K.
