“…This model has been effectively amplified to depict different attractive nano frameworks and plays a noteworthy part in understanding attractive magnetic properties [36][37][38]. There are structures that can be described by multiple models, such as the Ising model, which is often considered a logical and reasonable choice [39][40][41][42]. In this research, the Monte Carlo simulation is applied to simulate the magnetization plateaus of the fullerene-type core/shell structure.…”

This paper concerns the investigation of the critical (HC) and the saturation (HS) magnetic fields behavior of the studied system as a function of different physical parameters. The Monte Carlo method is used to study the magnetic properties of the ferrimagnetic behavior of a double fullerene X60 core/shell-like nanostructure. Based on the Ising model, we focus our study on a system formed by a double sphere core/shell. The two spheres contain the spins  = ± 1/2 in the core surrounded by the spin S = ± 1, 0 in the shell. Various types of magnetization curves have been established, depending on the competition among the exchange couplings, the crystal fields, and the temperature. The study reveals that the saturation magnetic field (Hs) is significantly influenced by variations in all exchange coupling parameters, whereas the critical magnetic field (Hc) is only mildly affected by these parameter variations. Moreover, the crystal field and temperature both influence the critical and saturation magnetic fields. Keywords: Double fullerene core/shell-like structure, Magnetization plateaus, Monte Carlo simulations, Critical and saturation fields, External magnetic field.

“…Attendance of magnetic moment in the structure of these materials, due to specific atoms, molecules, ions, or domains with a particular spin rotation, has made them more and more attractive in various fields of knowledge ( 3 ). According to the bulk magnetic susceptibility or flux density ratio between the interior and exterior of any materials, they can be categorized into five types as follows: diamagnetic ( 4 ), paramagnetic ( 5 ), ferromagnetic ( 6 ), ferrimagnetic ( 7 ), and antiferromagnetic ( 1 ).…”

Helminth Eggs as a Magnetic Biomaterial: Introducing a Recognition Probe

Parasitic helminths, despite their known negative impact (biomaterial) on human health and animal production, have fascinating features. In this study, we find fantastic magnetic properties in several forms: inductor [between 20.10 and 58.85 (±2.50) H], source of detectable electrical voltage [from +0.5 to 7.3 (±0.1) V, vs. the ground, GND, measured by an AVO meter] and different inductor magnitude [between 3.33 and 41.23 (±0.76)] μH, detected by electrochemical impedance spectroscopy as well as frequency scannable electromagnetic wave horn) in several frequencies (including 100, 120, Hz, and 1, 10, 100 kHz) in “Fasciola hepatica”, “Parascaris equorum” (with and without larvae), “Dicrocoelium dendriticum,” “Taenia multiceps”, and “Moniezia expansa” eggs. This claim is attributed to some surprising characteristics, including superior inductance and intrinsic magnetic susceptibility. This feature along with a close relationship to helminth egg structure, is a novel probe with acceptable reproducibility (RSD > 8.0%) and high enough trustworthiness for adequate differentiation in their magnitudes, relatively. These traits were measured by the “Single Cell Rrecording” methodology using a three-microelectrode system, implanted to each egg at the Giga ohm sealed condition (6.08 ± 0.22 GΩ cm−1, n = 5). The reliability of these results was further confirmed using multiple calibrated instruments such as a high-resolution inductance analyzer, LCR meter, impedance spectrometer, potentiometer, and an anomalous Hall effect (Magnetic field density) sensor. In addition, the critical role played (Synergistic Effect) by water-like molecules as the intermediate medium, besides the partial influence of other compounds such as dissolved oxygen, are investigated qualitatively, and specific relation between these molecules and magnetic field creation in helminth eggs was proved. These intrinsic characteristics would provide novel facilitators for efficient arriving at the researchable bio-based magnetic biomaterials, besides innovative and real-time identification probes in the “Parasitology” fields.

“…There have been efforts to study trilayer or three-layered superlattices via different approaches such as Monte Carlo simulation (MC) [14,16] and mean-field approximation (MFA) [17]. We also cite the study of extended ferrimagnetic structure analyzed within Monte Carlo method [18] The effects of dilution (or disorder) to such materials is significant since the truly homogenous models are only an idealization and real magnets always have some sort of impurities present in them. Even though the single spin trilayer magnetic systems do not need any kind of dilution to show the compensation phenomenon unlike bilayers and multilayers, the question of whether the Neel temperatures remain same under dilution is not answered.…”

A two-dimensional spin-1/2 trilayer magnetic system with quenched non-magnetic impurity is studied. The lattice is formed by alternate layers of two different theoretical atoms A and B arranged in a particular fashion A-B-A. The compensation point appears below the critical temperature, for which total magnetization of the system becomes zero even though the sublattice magnetization has a nonzero value. For a range of values of the relative interaction strength in the Hamiltonian, a compensation point is observed. We considered the Ising mechanics and employed the Monte Carlo method to determine the compensation point and critical temperature of the system. However, the effects of impurity in such systems are still not well studied. With that in mind, we address the effects of random non-magnetic impurity in the trilayer system. We also investigate the lattice morphologies in the presence of compensation and dilution and finally obtain the three-dimensional phase diagram for selected Hamiltonian parameters and impurity concentration.
