Temperature dependence of interlayer coupling in Fe/Cr/Fe wedge samples: static and dynamic studies

Abstract The interlayer coupling in Fe/Cr/Fe layer system with wedge-type chromium spacers was investigated as a function of chromium thickness and temperature using Kerr magnetometry and Mandelstam–Brillouin light scattering techniques. The system with a moderate roughness demonstrates an interlayer coupling which can be well described in the frame of the biquadratic coupling model. On the contrary, the smoother sample shows the interlayer coupling, which can be perfectly described by the proximity magnetism model, proposed by Slonczewski.
