Dielectric Properties of Ovalene-Like Nanostructure with RKKY Interactions: Monte Carlo Study

Abstract

In this study, we investigated the dielectric properties of ovalene-like nanostructure with RKKY (Ruderman–Kittel–Kasuya–Yoshida) interactions, using Monte Carlo simulations. Nanosystem consists of an ovalene-like nanostructure with mixed spins [Formula: see text]-7/2 and S-1, separated by non-electric layers (NEL). We investigated the effect of the non-electric layers, external longitudinal electric field and ferrielectric exchange coupling on polarization and dielectric susceptibility of the nanostructure. We find that the transition temperature is affected by an increase in the number of non-electrical layers. These results can enrich the dielectric properties of ovalene-like nanostructure for future nanotechnology applications.

Exploring dielectric phenomena in sulflower-like nanostructures via Monte Carlo technique

“…/ We employ the MCt with the Metropolis algorithm to examine the dielectric characteristics of a sulflower-like structure. It is worth noting that in our previous research, we effectively utilized the MCt to inspect the magnetic and dielectric characteristics of various types of nanostructures [32][33][34][35][36][37]. Furthermore, the application of an external electric field in the study of dielectric properties is crucial for understanding the response of materials to electric fields, characterizing dielectric behavior, determining polarization, dielectric susceptibility, electric hysteresis cycles, studying phase transitions, and manipulating material properties [17,18,35,36,38,39].…”
