“…There are various theories for this phenomenon. According to Lu et al [4] the preferential absorption of intermediate species prevents normal deposition. As the current density increases, the conditions for hydrogen regeneration become more suitable.…”

“…Thin films with thick of submicron and properties caused by their two main features including low thickness and high ratio of surface area with many applications in modern technologies. Some of these features included the increase in resistivity, light interference, tunneling, surface magnetization and critical temperature change of superconductors [4]. According to the performance and properties of the films, they can also be used to improve technologies such as solar cells, sensors, optical applications, electronics, and ferroelectrics [4][5].…”

This study is an attempt to produce surface nanocrystalline composite of Fe-Co-TiO2 at various current densities in the range of 20 to 50 mA/cm 2 via pulse electrodeposition method. The prepared composites were characterized by field emission scanning microscope (FESEM), electron dispersive spectrum (EDS), Vickers microhardness, vibrating sample magnetometer (VSM), and x-ray diffraction techniques (XRD). The results showed that the formation of cauliflower morphology was preferred at lower current densities. Moreover, the higher current densities enhanced the Fe content and at the same time diminished the Co and TiO2 contents of prepared surface composites. XRD patterns and Rietveld analysis confirmed the formation of combinations of BCC (as dominant) and FCC phases. Higher current density enhanced the saturation magnetization and decreased lower coercivity due to the higher Fe content and the reduction of TiO2 nanoparticles in coatings. In addition, the lowest coercivity and highest saturation magnetization were gained at 50 mA/cm 2 , while, the maximum microhardness obtained at 30 mA/cm 2 .

“…However, XRD peaks of nanorods indicate the presence of fcc phases, although bcc α-FeCo dominated the overall composition. The γ-Co peaks correspond to 2θ = 44° and 75° and are assigned to the fcc phase . No peaks of magnetite were detected in either sample, indicating the nanomaterials with no ferrite impurities.…”

Herein, we demonstrate that very high electromagnetic (EM) shielding efficiency can be achieved by dispersing nanoengineered FeCo anisometric nanostructures in a poly(vinylidene difluoride) matrix in the presence of conductive nanofillers (multiwall carbon nanotubes, MWCNTs). The FeCo nanorods (∼800 nm) and nanocubes (∼100 nm) were fabricated by a facile surfactant and polymer-assisted one-pot borohydride reduction method. The growth mechanism depicted a two-directional growth for cubes, whereas for nanorods, a unidirectional growth pattern across the (110) plane was evident. A total shielding effectiveness (SE) of -44 dB at 18 GHz was achieved for a particular combination of FeCo nanorods and MWCNT, and for nanocube-based composites, it was found to be -39 dB at 18 GHz. It was observed from zero field cooled-field cooled curves that the samples displayed room temperature ferromagnetism. An excellent correlation between high aspect ratio FeCo nanorod and superior EM absorption (89%) was explored, pertaining to the fact that nanorods possessed higher magnetic saturation (177.1 emu/g) and coercivity (550 Oe) in contrast to the nanocubes with similar composition. Furthermore, theoretical insight into the mechanism revealed a high degree of interface scattering between conductive MWCNT and magnetic loss components, giving rise to an excellent synergy between magnetic and dielectric parts.

“…There are many techniques by which we can do the magnetic characterization [20][21][22][23]. Among all the available methods to characterize magnetic properties, magnetic force microscopy (MFM) is the least explored and could be the most potent one if explored extensively.…”
