Hysteresis loops and dielectric properties of a mixed spin Blume-Capel Ising ferroelectric nanowire

The critical and hysteresis behaviors of a ferrielectric Blume-Capel nanowire are studied using the Ising model with mixed spins-(12, 1) in the presence of both an external longitudinal electric (Ez) and crystal anisotropy (D) fields. We use the Monte Carlo simulations (MCs) to examine the influence of Ez, D and the exchange interactions on the compensation and critical temperatures, the specific heat, the dielectric susceptibility and the internal energy of the system. Our theoretical predictions are in accordance with some experimental and theoretical results.
