From: Tailoring the magnetic anisotropy of Py/Ni bilayer films using well aligned atomic steps on Cu(001)
(a) Hard axis (H parallel to the steps) longitudinal hysteresis loops from vicinal Cu/Py(10 ML)/Ni/Cu(001). The Ni film enhances the step-induced magnetic anisotropy. (b) Anisotropy field versus Py thickness for vicinal Cu/Py/Ni(4.8 ML)/Cu(001) and Cu/Py/Ni(9.0 ML)/Cu(001). The same slope of the two curves shows that the Py volume anisotropy (
) remains the same for 4.8 ML<dNi < 9.0 ML.
