Special Issue Information

Dear Colleagues,

Magnetic materials are unique materials that are present in nature, including insects, bacteria, and several animals. For example, salmon use magnetic materials present in their nasal fossa for migration. With the development of nanotechnology, different magnetic materials have been discovered as storage materials, generators, motor components, transformers, magnetic shape memory, and magnetic devices. There are different types of magnetic materials in solids, such as metal oxides, metals, and magnetic alloys. However, in their colloidal state, they are in the form of nanofluids, ferrofluids, and magnetic fluids. Different classes of magnetic materials are used in several applications. However, in addition to general applications, magnetic materials are also used as bio-magnetic materials in different ways, such as therapy and for diagnosis purposes. The major application of bio-magnetic materials are MRI (magnetic resonance imaging) images, magnetic therapy, hyperthermia, drug delivery, molecular tracers, and as magnetic markers for the detection of infection or disease. Hence, to fabricate novel magnetic materials or bio-magnetic materials for different applications, substantial effort and further development are still required.

Herein, we report the synthesis of nanoparticles and doping of Cu-doped Co–Zn ferrites using the auto-combustion sol–gel synthesis technique. X-ray diffraction studies confirmed the single-phase structure of the samples with space group Fd3m and crystallite size in the range of 20.57–32.69 nm. Transmission electron microscopy micrographs and selected area electron diffraction patterns confirmed the polycrystalline nature of the ferrite nanoparticles. Energy-dispersive X-ray spectroscopy revealed the elemental composition in the absence of any impurity phases. Fourier-transform infrared studies showed the presence of two prominent peaks at approximately 420 cm−1 and 580 cm−1, showing metal–oxygen stretching and the formation of ferrite composite. X-ray photoelectron spectroscopy was employed to determine the oxidation states of Fe, Co, Zn, and Cu and O vacancies based on which cationic distributions at tetrahedral and octahedral sites are proposed. Dielectric spectroscopy showed that the samples exhibit Maxwell–Wagner interfacial polarization, which decreases as the frequency of the applied field increases. The dielectric loss of the samples was less than 1, confirming that the samples can be used for the fabrication of multilayer inductor chips. The ac conductivity of the samples increased with increasing doping and with frequency, and this has been explained by the hopping model. The hysteresis loops revealed that coercivity decreases slightly with doping, while the highest saturation magnetization of 55.61 emu/g was obtained when x = 0.1. The magnetic anisotropic constant was found to be less than 0.5, which suggests that the samples exhibit uniaxial anisotropy rather than cubic anisotropy. The squareness ratio indicates that the samples are useful in high-frequency applications. Full article
