Magnetic properties of a bi-fullerene-like structure, X60-Y60, with RKKY interactions in the Blume–Capel model

Abstract

In this paper, we study the influence of the physical parameters on the thermal and magnetic properties of a nano-particle of bi-fullerene-like structure X[Formula: see text]-Y[Formula: see text] separated by nonmagnetic spherical surfaces, using the Metropolis Monte Carlo (MC) simulations. The coupling between the two spheres containing the spins [Formula: see text] = 3/2 and the spins S = 7/2 belongs to the core and shell, respectively. This study is based on the RKKY (Ruderman–Kittel–Kasuya–Yoshida) interaction type. To complete this work, we carry out the hysteresis cycles of the studied system for different nonmagnetic surface (NMS) numbers.

Emergence of Multiple Hysteresis Cycles and Polarization Plateaus: A Monte Carlo Investigation of Fullerene-Like System

“…Moreover, Blume-Capel model was used to investigate the fullerene-like systems. 19,[46][47][48] In our investigation, we used 10 6 Monte Carlo steps per spin to get our data, removing the first 10 5 steps to make sure the fullerene-like system reaches equilibrium (Fig. 1).…”

“…19,20 In recent years, Monte Carlo simulations have played a crucial role in improving our understanding of various physical phenomena in materials science. These simulations have been used in a variety of research studies, including the magnetic properties of a bi-fullerenelike structure, X 60 -Y 60 with RKKY interactions, 19 magnetic properties in fullerene-like structures: X 20 , X 60 , or X 70 , 20 magnetic properties of mixed spin in a fullerene X 30 Y 30 -like structure, 21 dielectric properties and compensation behaviors of a monolayer naphthalene-like nano island, 22 dielectric properties of mixed spin-3/2 and spin-5/2 Ising ferrielectric nanowires, 23 dielectric properties of a monolayer nanographyne structure, 24 the investigation of the magnetic properties of core-shell Ising nanowires. 25 They have also been used to study dynamic phase transitions, electronic and magnetic properties in double perovskite materials such as Ba 2 NiWO 6 and Sr 2 NiWO 6.…”

Hysteresis in core/shell nanowire with mixed spin Ising

“…More recently studies with MCS in hexagonal ferrimagnetic Ising nanowire [12], Blume Capel model [29] and Quantum Monte Carlo [13] show the appearance of plateaus and different forms of hysteresis loops. However, mixed spin core/shell systems have been less investigated.…”

“…Thus, they have been used in many applications, such as medical treatment of HIV [3][4][5], biomedical [6], magnetic refrigeration [7], drug delivery [8] and biological waste-water treatment [9]. Fullerene and its derivatives have extraordinary and impressive properties, such as superconductivity [10], magnetism [11][12][13][14][15][16][17], thermodynamic properties [18] and electrical properties [19][20][21].
