“…A number of samples for undoped SrTiO 3 , Zr-doped SrTiO 3 and (Zr, Ni) co-doped SrTiO 3 have been synthesized using the standard solid state reaction method [33,34]. For the starting materials, proper combinations of analytical grade SrCO 3 (98% pure), TiO 2 (99.9% pure), ZrO 2 (99.9% pure) and NiO (99.9% pure) were used with desired stoichiometric ratio.…”

We synthesized strontium titanate SrTiO3 (STO), Zr doped Sr1-xZrxTiO3 and (Zr, Ni) co-doped Sr1-xZrxTi1-yNiyO3 samples using solid state reaction technique to report their structural, electrical and magnetic properties. The cubic P m-3m phase of the synthesized samples has been confirmed using Rietveld analysis of the powder X-ray diffraction pattern. The grain size of the synthesized materials was reduced significantly due to Zr doping as well as (Zr, Ni) co-doping in STO. The chemical species of the samples were identified using energy-dispersive X-ray spectroscopy. We observed forbidden first order Raman scattering at 148, 547 and 797 cm −1 which may indicate nominal loss of inversion symmetry in cubic STO. The absence of absorption at 500 cm −1 and within 600-700 cm −1 band in Fourier Transform Infrared spectra corroborates Zr and Ni as substitutional dopants in our samples. Due to 4% Zr doping in Sr0.96Zr0.04TiO3 sample dielectric constant, remnant electric polarization, remnant magnetization and coercivity were increased. Notably, in the case of 4% Zr and 10% Ni co-doping we have observed clearly the existence of both FE and FM hysteresis loops in Sr0.96Zr0.04Ti0.90Ni0.10O3 sample. In this co-doped sample, the remnant magnetization and coercivity were increased by ∼1 and ∼2 orders of magnitude respectively as compared to those of undoped STO. The coexistence of FE and FM orders in (Zr, Ni) co-doped STO might have the potential for interesting multiferroic applications.

Investigation of Structural and Microbial Properties of Samarium-Doped Nickel-Strontium Ferrite Nanoparticles Prepared via the Sol-Gel Route

et al. 2023

View full text Add to dashboard Cite

Nickel and Samarium-doped strontium ferrite nanoparticles were synthesised using the sol-gel autocombustion method. The micro-structural characteristics of the ferrite were investigated using X-ray diffraction (XRD) and eld emission scanning electron microscopy (FE-SEM). The particle size was determined to be between 30 and 60 nm. The vibrating sample magnetometer (VSM) revealed a strong magnetization with paramagnetic behaviour, and the existence of all elements was veri ed by energy dispersive X-ray spectroscopy (EDS). According to the BET adsorption isotherm, total surface area ranges from 13.77 m 2 g -1 to 28.49 m 2 g -1 . At P/Po (0.99), the total pore volume ranges from 0.02 cm 3 g -1 to 0.04 cm 3 g -1 . The average pore width ranged from 3.5 nm to 6.5 nm, and the isotherm demonstrates type III with an H 3 hysteresis loop. The material shows 84% thermal stability and these synthesized nanoparticles are showing activity against both Gram Positive and Gram-Negative bacterial pathogens.
