Abstract:
LuMnO3 is one of the most representative ferroelectric materials with hexagonal structure. The aim of this study was Modeling and Simulation of Ferroelectric Hysteresis Loop Parameters of LuMnO3. Because of their exceptional characteristics, LuMnO3 based compositions have been the focus of considerable investigation among ferroelectric materials. The parameters remnant polarization, spontaneous polarization, and coercive electric field were used in the Simulation to obtain the ferroelectric hysteresis loop in this study as well as the value of Pmax=0.2244W ,efficiency (ƞ)=94.4 ,Fill factor (FF)=0.6 were calculated , which was done using MATLAB program. The steps followed in these modeling methods were appropriate m modeling functions for each simulation were described. Next, MATLAB coding was used for each function by setting all of the necessary inputs and finally, the output result was displayed. On the parameters of the Ferroelectric hysteresis loop of LuMnO3, the effects of applied electric field, temperature, and were investigated. As the electric field increases: the coercive field (Ec), saturation polarization (Ps), remnant polarization (Pr) and area of hysteresis loop (A) all increase. On the other hand, the coercive electric field (Ec), remnant polarization (Pr) and area of hysteresis loop decrease when the temperature rises
