From: High magnetoelectric coupling of Metglas and P(VDF-TrFE) laminates
LDV measurements on vertical displacement on the laminate sample over the whole surface area top view followed by schematic side view. (a) The vertical displacement at the P(VDF-TrFE)/PEDOT:PSS side when the laminate sample surface is excited perpendicular at the magnetoelastic resonance frequency (109 kHz). (b) The vertical displacement at the P(VDF-TrFE)/PEDOT:PSS side when the laminate sample is excited at a tilted angle of 2.3° at the resonance frequency (109 kHz), to be able to get a clearer view of the surface longitude movement. (c) The background signal at the P(VDF-TrFE)/PEDOT:PSS side obtained with no excitation. (d) Simulated vertical displacement amplitudes for Metglas with a layer of PVDF to verify the magnetic mode coupling to the mechanical mode and the pattern visible from LDV.
