Angular Response of Magnetostrictive Thin Films

Figure 5

Representative magnetostriction loops (solid line: bending; dot line: torsion) of S/Py/TbFe₂-coupled bilayers at different driving field angle (𝜙 = 15, 75, 90, 105, 165, 195° : (a)–(f)); graphical representations (i) and (ii) reveal the deviation of easy axis from the long axis of the sample.
