Abstract
The magnetic properties of Co/Si multilayers with different thicknesses of Co (2–42 nm) and Si (0.3–10 nm) layers produced by high-frequency ion sputtering have been studied. Peculiarities of the microstructure of multilayered films and regularities of their magnetization with varying the magnetic field (0–500 Oe) and temperature (4.2–300 K) have been determined. A conception of the partial interlayer mixing with the formation of surface interfaces with a granular magnetic structure has been used for a model description of the structural and chemical states and magnetic properties of the multilayers. The relative volume of interfaces and parameters of their elements—granules—vary depending on the nominal magnitudes and relationship between the layer thicknesses. This leads to specific hysteretic effects. The interlayer interaction of domain walls is likely to play a certain role in the formation of the hysteretic properties.
