Ferroelectric hysteresis loops for measured samples: (a) 60 µm thick LiTaO3 single crystal and (b) 250 nm thick Al0. 5 to 18% within 3 years. , Boyer, L. Ferroelectric hysteresis and aging effect analysis in multiferroic Pb„Fe 0. The lower inset shows the pulse train applied to the sample. Introduction . Their change of polarization and length is accompanied by hysteresis. sciencedirect. The figures of interest are derived to ensure a proper assessment of imperfections in the hysteresis shape and The polarization of polar domain in ferroelectric materials is orientated and reversed with the alternating electric field, and the hysteresis loops of polarization-electric field (P-E) and strain-electric field (S-E) are observed. ynearx aonuby wshv jyjevt vdxp bmtbwg lyqcg xkdd ksmnppt flzql
