Impact of doping Gd3+rare earth ion on structural, magnetic, and optical properties of cobalt and nickel ferrite nanomaterials

Gadolinium doped zinc ferrite nanoarchitecture reinforced with a carbonaceous matrix: a novel hybrid material for next-generation flexible capacitors

“…Since the ionic radius of Gd (0.938 Å) is much greater than that of iron (0.645 Å), Fe substitution with Gd at octahedral sites may account for the observed rise in lattice constant from 8.46 to 8.48 for the GZFO nanomaterial. 24 The presence of these strong diffraction peaks in the PXRD pattern is indicative of the crystalline nature of the ZFO and GZFO nanomaterials. Additionally, the lack of any additional peaks belonging to any impurity phase, even after Gd doping, further demonstrates the phase purity of the nanomaterials that were produced.…”

Lanthanum substituted Ni-Zn ferrite (Ni0.75Zn0.25Fe2O4) nanomaterial and its composite with rGO for degradation of binary dyes under visible light irradiation

“…In order to prevent the recombination of electron-hole pairs, it is evident that rGO play a crucial function in promoting the photocatalytic performance of pure NZF and La 3+ substituted NZF NPs [61]. Moreover, all of the samples exhibited a weak emission peak at 520 nm which may be attributed to oxygen vacancy, in addition to the presence of the intense peak at 460 nm [64].…”

Comparative study between oxide/soft ferrite, oxide/hard ferrite, and soft/hard ferrite nanocomposites: structural, electrical, and magnetic properties

“…Biomedicine, biosensing, agriculture, catalysis, and energy storage applications are a few of these uses [1,2]. It is possible to enhance certain magnetic nanomaterials by including impurities [3][4][5][6], altering the production procedure [7][8][9], or combining them into composite materials [10][11][12]. A nanocomposite material is made up of many phases, each of which has at least one, two, or three dimensions that are smaller than 100 nm.…”
