Magnetic hysteresis loops for a Metglas®/PMN-PT heterostructure with (solid curve) and without (dash curve) the application of electric field. Inset (a) is a schematic diagram of the MF heterostructure depicting measurement geometries, and (b) the dependence of CME effect in response to applied magnetic fields.
Variation in CME effect with time in different time domains for the Metglas®/PMN-PT heterostructure. A square waveform electric field (e) of 8 kV/cm was applied. (a) Initial 100 s, (b) 50 s after 100 s, (c) 50 s after 500 s, and (d) 50 s after 2500 s.
Variation in CME with (a) number of E-field cycles, and (b) time after initial excitation of the Metglas®/PMN-PT heterostructure. In panel (a) the square hollow symbol represents the measured value after termination of continuous cycling at 1000 cycles followed by a rest period of 60 min. In panel (a) the solid curve is a guide to the eyes, whereas in (b) the dash curve is the best fit to Eq. (2).
