Magnetic Nanoparticles and Thin Films

Topic Information

Dear Colleagues,

Magnetic nanoparticles (MNPs) and thin films are pivotal in modern science and technology due to their unique magnetic, structural, and functional properties. MNPs are typically made of materials like iron oxide, cobalt, or nickel; exhibit superparamagnetism; and have a high surface area and excellent magnetic responses. Magnetic nanoparticles and thin films are materials of immense scientific and technological interest owing to their exceptional magnetic properties and prospective applications in various fields. Magnetic nanoparticles, typically ranging in size from 1 to 100 nanometers, exhibit unique phenomena like high surface-to-volume ratios and superparamagnetic responsiveness, making them ideal for biomedical applications (e.g., drug delivery, imaging), magnetic data storage, and environmental remediation. Recent advancements focus on synthesizing these materials with precise control over properties, developing hybrid systems, and exploring their quantum and nanoscale behaviors for future applications in flexible electronics, neuromorphic computing, and sustainable technologies. Thin films, on the other hand, are nanoscale magnetic coatings with applications in magnetic sensors, spintronic devices, quantum computing components, and advanced storage technologies. Their performance is influenced by parameters such as their composition, structure, thickness, and fabrication techniques. The development and manipulation of these materials are crucial for advancing technologies in energy, electronics, and healthcare. We welcome original research articles or comprehensive reviews focusing on cutting-edging developments in and applications of magnetic nanoparticles and thin films. The topics of interest for publication include, but are not limited to, the following:

• Biomedical Applications: drug delivery, magnetic resonance imaging (mri), hyperthermia therapy, diagnostics, biocompatible coatings, and biosensors.
• Environmental Applications: water purification and pollution control.
• Magnetic Applications: data storage and spintronics.
• Catalysis.
• Energy Applications: battery technology, magnetocaloric effects, hybrid systems combining mnps with polymers or ceramics, fuel cells, and supercapacitors.
• Electronics: semiconductors, displays, and solar cells.
• Optics: antireflective coatings and mirrors and filters.
• Protective Coatings: corrosion and scratch resistance.
• Sensors.
• Advanced Functional Materials.

In this article, the motion control of ferromagnetic particles through varying a non-invasive magnetic field is addressed. Within an experimental test bench, three experiments are proposed to verify motion control, which consist of control of the distance between electromagnets, retention of particles over the flow, and manipulation of the direction of particle flow at a “Y”-type bifurcation emulating an “OR” gate. At each experimental stage, instrumented test benches were integrated with current, distance, and flow sensors, enabling measurement and feedback of the system’s physical variables. These benches were configured using pulse-width-modulation (PWM) and Proportional–Integral–Derivative (PID) controllers to regulate the current supplied to the electromagnets and, thereby, control the intensity of the induced electromagnetic field according to the requirements of each experiment. Different study cases were defined to analyze the operational limits of the system by varying the current influencing the electromagnetic field and the configuration of the electromagnets. The results describe the response of the magnetic field, the induced force, and the behavior of the suspended particles under each condition, providing elements to characterize the performance of the electromagnetic system in operational scenarios and contributing to the understanding of the phenomena associated with the non-invasive manipulation of ferromagnetic particles by means of controlled magnetic fields.

Manganese oxides (manganites) are among the most studied materials in condensed matter physics due to the famous colossal magnetoresistance and very rich phase diagrams characterized by strong competition between ferromagnetic (FM) metallic and antiferromagnetic (AFM) insulating phases. One of the key questions that remains open even after more than thirty years of intensive research is the exact conductivity mechanism in insulating as well as in metallic phases and its relation to the corresponding magnetic structure. In order to shed more light on this problem, here, we report magnetotransport measurements on sintered nanocrystalline samples of the very poorly explored manganites ${\mathrm{Ca}}_{1-x}{\mathrm{Gd}}_x{\mathrm{MnO}}_3$ with $x=0.05$ and $x=0.10$, in the temperature range 2–300 K, and in magnetic fields up to 16 T. Our results indicate that both compounds at low temperatures exhibit metallic behavior with a peculiar resistivity upturn and a large negative magnetoresistance. We argue that such behavior is consistent with a Kondo-like scattering on Gd impurities coupled with the percolation of FM metallic regions within insulating AFM matrix. Full article
