“…Thus, cation inversion is responsible for the changes in the properties of ferrites. There are certain methods such as laser irradiation (Tawfik et al, 2002;Ateia et al, 2019), ion implantation (Sharma et al, 2023a), gamma-irradiation (Raut et al, 2018) and heavy ion irradiation (Nongjai et al, 2023) which are well known to change the physical behavior of ferrites in a controlled way. This review focuses on the cation inversion manipulation and associated changes with swift heavy ion irradiation.…”

The size-dependent behavior of nanostructured ferrite is well established. Various physical properties such as magnetic, optical and electrical exhibit strong size dependence. Thus, any treatment which causes a change in size is able to modify the characteristics of ferrites. The result of this effect can be seen when these ferrites are subjected to an intense heavy ion beam which modifies the physical properties of ferrites. This modification is related to cation redistribution owing to size change in most of the cases under heavy ion irradiation. However, few recent studies show that cation redistribution may occur under ion irradiation even though no size change is observed. The objective of this review is to highlight this effect in ferrite systems which ultimately may provide ample opportunity for its potential applications.

“…The preparation method for spinel ferrite nanoparticles can be achieved through the following steps: First, an appropriate synthesis method, such as sol-gel [109], hydrothermal [101], or co-precipitation [90], is used to mix suitable metal salts with basic precipitants, forming a precipitate. Next, through appropriate washing, centrifugation, and drying processes, the precipitate is transformed into nanoparticle form.…”

Gas-sensing technology has gained significant attention in recent years due to the increasing concern for environmental safety and human health caused by reactive gases. In particular, spinel ferrite (MFe2O4), a metal oxide semiconductor with a spinel structure, has emerged as a promising material for gas-sensing applications. This review article aims to provide an overview of the latest developments in spinel-ferrite-based gas sensors. It begins by discussing the gas-sensing mechanism of spinel ferrite sensors, which involves the interaction between the target gas molecules and the surface of the sensor material. The unique properties of spinel ferrite, such as its high surface area, tunable bandgap, and excellent stability, contribute to its gas-sensing capabilities. The article then delves into recent advancements in gas sensors based on spinel ferrite, focusing on various aspects such as microstructures, element doping, and heterostructure materials. The microstructure of spinel ferrite can be tailored to enhance the gas-sensing performance by controlling factors such as the grain size, porosity, and surface area. Element doping, such as incorporating transition metal ions, can further enhance the gas-sensing properties by modifying the electronic structure and surface chemistry of the sensor material. Additionally, the integration of spinel ferrite with other semiconductors in heterostructure configurations has shown potential for improving the selectivity and overall sensing performance. Furthermore, the article suggests that the combination of spinel ferrite and semiconductors can enhance the selectivity, stability, and sensing performance of gas sensors at room or low temperatures. This is particularly important for practical applications where real-time and accurate gas detection is crucial. In conclusion, this review highlights the potential of spinel-ferrite-based gas sensors and provides insights into the latest advancements in this field. The combination of spinel ferrite with other materials and the optimization of sensor parameters offer opportunities for the development of highly efficient and reliable gas-sensing devices for early detection and warning systems.

“…In order to carry out a solid comparative study, a tabulation sheet (vide Table 1) is prepared here based on some published literatures of recent past and is relevant to this work. Raut et al 61 demonstrated the zinc ferrite-based ammonia sensor synthesized by the sol-gel autocombustion method. They were able to find a maximum response of $95% on 400 ppm NH 3 exposure at room temperature by treating the sample with γ-radiation.…”

This article introduces a ternary nanocomposite‐based flexible thin film ammonia sensor developed on transparent polyethylene terephthalate (PET) substrate in the well‐known in situ chemical oxidative polymerization technique. The nanocomposite consists of three different materials: polyaniline (PANI), reduced graphene oxide (rGO), and zinc ferrite (ZF). Keeping the PANI amount constant, seven PANI/rGO/ZF (PRZ) samples are produced by performing stoichiometric variation between rGO and ZF. Later on, various structural, morphological, and spectroscopic analysis of all the composite materials is accomplished with field emission scanning electron microscopy (FESEM), high‐resolution transmission electron microscopy (HRTEM), X‐ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), and ultraviolet–visible spectroscopy (UV–Vis). The sensing performance of the as‐produced sensors toward ammonia (NH3) is examined in the concentration range from 250 ppb to 100 ppm. The study reveals the excellent sensing ability of the PRZ3 sensor (rGO = 30%, ZF = 20%) achieving minimum and maximum responsivity values of ~51% and ~1052%, respectively, at the lowest (250 ppb) and highest (100 ppm) concentration of ammonia. The sensor also exhibits admirable repeatability, good dynamic responsivity, rapid response (tres ~2.9–5 s), moderately faster recovery (trec ~37.9–69.7 s), superb linearity against ppm variation (R2 ~ 0.989), low detection limit (~123 ppb), and exceptional selectivity toward ammonia. The substrate temperature variation divulges that room temperature (30°C) is the ideal temperature for getting outstanding responsivity of the sensor. The study is further accompanied by humidity variation in the incoming air and bending flexibility test of the substrate. A compulsory and legitimate model regarding the sensing mechanism is presented at the end.
