“…XRD peaks reveal the presence of single-phase cubic spinel structure for AP and annealed samples at 500 C which agree well with JCPDS data (card numbers 01-074-2403 and 01-074-8055) and Z-type hexagonal structure for T ! 600 C which agree well with JCPDS data (card number 01-073-2036) [14,15]. XRD patterns prove the transformation of crystal structure phase from cubic to Z-type hexagonal by annealing at 600 C. This transformation of structural phase may assign to two reasons; (1) Cooperative distortion of Jahn-Teller effect (JTE) of Mn 3þ (d 4 ) ions.…”

“…4. The decrease of R explains the transformation process inside the crystal lattice as T increases, whereas the increase confirms improving the crystallization process and coalescence of small crystallites as T increases [15]. Increasing R may assign to the transformation of the thin amorphous layer at the nanoparticle surface into crystalline part with T. Fig.…”

“…The decrease of G A and G B may point to improving the crystallization process and chemical and cation order with T. The increase of G A and G B may assign to a random distribution of Sr 2þ and Mg 2þ ions amongst the A-and B-sites [28,29], and cation disorder of the samples due to transformation process [12,15]. Distributing the Fe 3þ ions among the A-and B-sites can be obtained by drawing the area ratio of B-to A-sites (B/A) against T as depicted in Fig.…”

Ferrites are of great interest for both fundamental science and technological applications due to their outstanding physical, chemical, and magnetic properties. Among various ferrites, Mg‐Zn ferrites is one of the best magnetic materials for researchers due to their unique properties such as high electric resistivity, Curie temperature, low coercivity, low eddy current, dielectric losses, low cost, and better environmental stability. This makes ferrites suitable for many applications such as power transformers, microwave devices, computer memories, logic devices, recording heads, loading coils, antenna rods, color monitoring tubes, telecommunications, hyperthermia, and so forth. Mg‐Zn ferrite nanoparticles have gained increased interest for many applications such as catalysts, antimicrobial potential, and sensors for the detection of combustible gases (CH4, CO, and CO2). In this brief review, the strategies used in the synthesis of Mg‐Zn ferrite nanoparticles are summarized. The different structural, morphological, magnetic, and electric properties of these ferrites are analyzed.

The present manuscript portrays environmental benign, cost‐effective and energy efficient green route way to synthesize Mg−Zn ferrite nanoparticles [Mg0.05Zn0.05Fe2O4 NPs] using Ocimum Basilicum leaf extract [OBLE]. X‐ray diffraction (XRD) analysis revealed that Ocimum Basilicum leaf extract mediated Mg−Zn ferrite nanoparticles [OBLE@Mg−Zn NPs] exhibit face centred cubic crystallinity with space group as confirmed by Rietveld refinement studies. Microstructural analysis illustrated uniform surface morphology with well interlinked grain with an average grain size of 35.6±0.12 nm. FTIR spectra showed existence of hydroxyl −OH group at 3403 cm−1 and C=C vibration at 2345 cm−1. Magnetic hysteresis loop (M−H loop) confirmed the superparamagnetic behaviour of OBLE@Mg−Zn NPs. Cytotoxic activity of OBLE@Mg−Zn NPs was carried out against breast cancer cell line MDA‐MB‐231. Dose dependent cell viability of cancerous cells depicted cytotoxic potential of OBLE@Mg−Zn NPs.
