Abstract: | The temperature-driven spin reorientation transition of magnetron
sputtered Ni/Si (111) systems has been studied. The relationship
between ac initial susceptibility and temperature of nickel films
with different thicknesses shows that the magnetization orientation
changes from in-plane to out-of-plane with the increase of
temperature. The temperature dependence of magnetoelastic,
magneto-crystalline, and magnetostatic anisotropies determines the
direction of the reorientation transition. The temperature-driven
spin reorientation transition is supported by Hall coefficient
measurements which show that its temperature dependence is similar
to that of susceptibility. |
