Abstract: The effect of chemical treatments on the surface morphology and local magnetic characteristics of thin films of a FeN alloy and thin-film structures comprising submicron layers of this alloy separated by a silicon dioxide interlayer has been studied by microscopic and magnetooptical techniques. It is established that chemical etching in the presence of a magnetic field strongly changes both the surface morphology and magnetic properties of samples. The local values of the saturation field and coercive force in thin-film structures upon the chemical treatment are significantly different, which is related to the appearance of inhomogeneities on the sample surface and the resulting increased influence of stray fields on the measured magnetic characteristics.
