“…Conventional electrical, electronic, and magnetic devices are based on ferrites. Ferrite nanoparticles are used in many equipment to suppress and dissipate high frequency noise levels caused by electromagnetic devices [10,11]. Ferrites have immensely changed magnetic, electrical, optical, and structural tunability and applications in different electronic technology [12], biomedical fields [13], energy storage [14], environmental protection [15], etc.…”

“…Spinel nanoferrites have a ceramic material structure consisting of iron oxide and other metallic elements [2]. Spinel nanoferrites have a significant variety of usages, including switching and high-frequency devices [11], removal of organic industrial contaminants [16], hyperthermia treatments [17], high-performance energystorage equipment [10], drug delivery for cancer treatment [18], and waste-water management [19]. The spinel structure ferrites also have been used in lithium-ion batteries [20] in antimicrobial [21,22], and microwave applications [23,24].…”

Nanoferrites play a pivotal role to resolve worldwide usage of electronic and microwave devices. Spinel ferrites have exceptional structural, morphological, and dielectric properties. The composition Zn0.5–xMg0.25+xCo0.25Cr1–xFe1+xO4 (ZMCCF) where x varies from 0-0.5 with the difference of 0.25 was synthesized via auto combustion (sol-gel) route. The structural, thermal, and dielectric characterizations were done to observe the responses of variation of x in designed nanoferrites. The designed nanoferrites with a variation of x experienced promising changes in structural, thermal, and dielectric responses. With the increase in frequency, the dielectric constant decrease which is the favorable trend of spinel ferrites based on Koop’s theory. This behavior is endorsed by the different cationic distributions in the spinel structure. The maximum value of the tangent loss at low frequencies reflects the application of these materials in medium frequency devices. Therefore planned spinel nanoferrites may beneficial for advanced electronics and microwave devices.

“…In recent, many reported on ZnO with single transition metal-doped prepared by different methods such as Mn-Co codoped [6], Fe-Ni codoped [7], Fe-Co codoped [8], Co-Cu codoped, and Cr-Fe codoped [9]. In recent, there are many other reported, magnesium doped with nano ferrites [10], calcium chromium magnesium nano ferrites [11], Ce-doped Co-Mg-Cd spinel nano-ferrites [12]. Many processes have been discovered to synthesize the nanostructure, they are coprecipitation [13], sol-gel [14], solvothermal [15,16,17,18], sonochemical [19][20], and polymeric citrate precursor [21].…”

The iron and Nickel co-doped in zinc oxide nano-particle, Zn1-x-yFexNiyO {(x=0, y=0), (x=0.05, y=0), (x=0, y=0.05), (x=0.03, y=0.02)} were prepared by Sol-Gel technique. This type of synthesis is used for the manufacture of a Field Effect Transistor (FET) detector which is extremely sensitive, secure, and capable of reproducing. It is also used for the detection of the Piperidine (CH2)5NH (hexahydro pyridone) chemical. The well-closed pack spherical nano-particles of the identified crystalline structure of the usual wurtzite hexagonal phase were achieved by characterization of X-Ray Diffraction (XRD). The blue shift was well observed of Co-doped samples as compared to un-doped or single-doped ZnO nanoparticle samples by UV-visible absorption spectrum. The Fourier Transform Infrared Spectroscopy (FTIR) reveals the existence of chemical bonding and functional groups are established and the occurrence of iron Fe in modes associated with iron Fe in addition to ZnO. The room temperature ferromagnetism was achieved in single or co-doped (Fe-Ni) with ZnO nanoparticles and is confirmed by magnetic characterization (VSM). It was perceived that magnetic saturation was improved in Fe-Ni Co-doped samples relative to pure or single doped. Also, the characterizations of samples show that the exchange interaction of Ni and Fe dominates over Ni-Ni and Fe-Fe interactions.
