Abstract:

The magnetic properties of planar Co/Si nanostructures with different nominal thicknesses of the magnetic (2-42 nm) and nonmagnetic (0.3-10 nm) constituent layers are studied in the temperature range 4.2-300 K. It is established that in the presence of Si layers the spontaneous magnetization of Co decreases and its temperature dependence changes, and magnetic hysteresis is modified. The interlayer influence is interpreted as being due to the diffusion of Si into the Co layers, which results in the formation of magnetically disordered boundary interfaces with low average magnetization. The depth of the interfaces depends on the nominal thickness of the Si layers and is estimated to reach 1.6 nm. A qualitative explanation of the characteristics of the magnetization of the experimental objects under the influence of a magnetic field and temperature is given in a model where the interfaces have a granular microstructure. Electron-microscope observations confirm some assumptions of the proposed model. (C) 2007 American Institute of Physics.
