Mössbauer spectroscopy, in a broad temperature interval of 12425 K, has been applied to
investigate the spin reorientation dynamics caused by the temperature induced magnetoelastic effect
on Alx um/Metglas 2605S2 20 um /Alx um trilayersx=0; 2.5; 5 and 20 um. It was found that
the angle between the average sample magnetization and gamma ray direction (perpendicular to the
sample plane) depends on the Al layer thickness. For temperatures smaller than 260 K, saturation of
spin reorientation, which can be controlled by adjusting the Al thickness, was reached for Al
thicknesses larger than and equal to 5 um. For a 20um Al thickness, changes in the 57Fe atom
spin and charge densities have also been observed. A simple spin model has been proposed to
describe qualitatively the spin reorientation effect as well as the influence of the Al thickness on the
spin reorientation sensitivity
