“…The role of the domain wall energy is essentially to hinder the material from demagnetizing and consequently increase coercivity. But reducing the number of domain walls allows the material to demagnetize easily, hence reducing H c [ 73 ]. Therefore, the material in this situation, with nearly zero H c , is regarded as superparamagnetic instead of ferrimagnetic.…”

“…In recent years bulk-nanostructuring using the cryomilling method got wide attention among scholars because of the energy-efficient nature compared to other NC production routes. Liquid phase NC materials synthesis includes processes, such as rapid solidification [58][59][60][61], electrodeposition [62][63][64], chemical precipitation [65,66], and sol-gel technique [67][68][69]. NC material synthesis in gaseous form is achieved by inert gas condensation [70][71][72], vapor deposition/sputtering [73][74][75][76][77], and plasma processing [78].…”

Nanostructuring is a commonly employed method of obtaining superior mechanical properties in metals and alloys. Compared to conventional polycrystalline counterparts, nanostructuring can provide remarkable improvements in yield strength, toughness, fatigue life, corrosion resistance, and hardness, which is attributed to the nano grain size. In this review paper, the current state-of-the-art of synthesis methods of nanocrystalline (NC) materials such as rapid solidification, chemical precipitation, chemical vapor deposition, and mechanical alloying, including high-energy ball milling (HEBM) and cryomilling was elucidated. More specifically, the effect of various process parameters on mechanical properties and microstructural features were explained for a broad range of engineering materials. This study also explains the mechanism of grain strengthening using the Hall-Petch relation and illustrates the effects of post-processing on the grain size and subsequently their properties. This review also reports the applications, challenges, and future scope for the NC materials.

The polycrystalline ferrite samples of NixCo1−xFe2O4 (x = 0.1, 0.3, 0.5, 0.7, and 0.9) are synthesized through the well‐known sol–gel method. The X‐ray diffraction (XRD) pattern confirms the cubic single‐phase spinel structure. Rietveld refinement indicates the absence of any other impurity phases in the samples. Additionally, XRD analysis reveals variations in lattice parameters corresponding to the doping. The Debye Scherer formula has been used to calculate the crystallite size of the samples, the crystallite size of the samples existing in the nanoregime. The results from field emission scanning electron microscopy confirm the morphological structure of the prepared samples. Additionally, the energy‐dispersive X‐ray spectra confirm the elemental composition and purity of the synthesized samples, validating the appropriateness of doping in the polycrystalline samples. The Raman spectra give the information about the vibrational modes in the sample. The Fourier transform infrared rays spectrum shows that the samples have a broad range of chemical interactions. The photoluminescence spectroscopy (PL) suggests strong luminescence in the visible range. PL spectroscopy provides that PL intensity decreases with increasing excitation wavelength due to nanosize of the particle.
