“…Diffusion coefficient increases with the increasing of temperature, therefore, the grain size increases [44]. Similar observations were reported for Li-Zn ferrites [28,45]. The microstructure of the samples was porous and it means that the ferrite Li 0.5 Sm 0.1 Fe 2.4 O 4 cannot be fully sintered at these temperatures.…”

“…Lithium ferrites can be synthesized by variety of techniques, such as high energy ball milling [22,23], solgel [24,25], auto-combustion method [25][26][27], solid state reaction [28][29][30], and co-precipitation [31]. To our best knowledge, the bulk magnetic properties of nanostructured LiSm ferrites, particularly synthesized by MA, have not been reported.…”

The effect of Sm content Li 0.5 Sm x Fe 2. 5-x O 4 (x = 0, 0.05, 0.1, and 0.2) and sintering temperature on the phase evolution, microstructure, and bulk magnetic properties of lithium ferrite prepared by mechanical alloying is investigated. XRD results of pure samples confirmed that the single ferrite phase is formed after sintering at 800°C; however, increasing of samarium content led to the formation of secondary phase (SmFeO 3 ) and enhanced intensity. The bulk magnetic properties decreased with increase Sm content and increased with sintering temperatures. Single-phase ferrites Li 0.5 Sm x Fe 2.5-x O 4 were produced by sintering of sample at 800°C, which is lower than the temperature associated with the conventional ceramic procedure.

“…both dielectric and magnetic component is a wellconsidered topic in the field of EMI shielding and RAMs [13][14][15][16][17][18]. As the electromagnetic radiation has both dielectric and magnetic component, so it is obvious that both dielectric and magnetic material is effective for the absorption of microwave radiation.…”

Multiwall carbon nanotube (MWCNT) based nanocomposites were prepared by a two-step process. Firstly, titanium dioxide (TiO2) coated MWCNT was prepared via sol-gel technique. In the second step, the acid modified MWCNTs were dispersed in the thermoplastic polyurethane matrix by solution blending process. Characterizations of the nanocomposites were done by X-ray diffraction analysis, X-ray photoelectron spectroscopy, Scanning Electron Microscopy, Transmission Electron Microscopy and Energy-dispersive X-ray spectroscopy. Microwave absorption studies of the nanocomposites were carried out in X-band region. The microwave absorption result was discussed with the help of complex permittivity and permeability of the prepared radar absorbing material (RAM). The result showed superior microwave absorption property of the composite containing both TiO2 coated MWCNT and magnetite (Fe3O4). This result is due to the effective absorption of both electrical and magnetic components of the microwave. RAM-MW, RAM-Ti, RAM-Ti@MW and RAMTi@ MW/Fe and showed the maximum reflection loss of –16.03 dB at 10.99 GHz, –8.4 dB at 12.4 GHz, –36.44 dB at 12.05 GHz and –42.53 dB at 10.98 GHz respectively. Incorporation of MWCNT enhanced the thermal stability of the composite which has been confirmed by thermogravimetric analysis
