Neodymium doped on the manganese‒copper nanoferrites: analysis of structural, optical, dielectric and magnetic properties

Influence of neodymium substitution on structural, magnetic and spectroscopic properties of Ni–Zn–Al nano-ferrites

“…The doping of neodymium (Nd 3+ ) in spinel ferritesdecreases the saturation magnetization, and alsoincreases the density and resistivity of the spinel ferrite due to unpaired electrons in the 4f orbital of Nd 3+ that give rise to ion with a nonmagnetic nature. 7 Moreover, the larger ionic radii Nd 3+ ions replace Fe ions at the octahedral site of the ferrites which results in improved magnetic and electrical properties of the ferrites for the high-frequency application. [8][9][10] X. Wu et al 11 synthesized Ni 0.5 Zn 0.5 Nd x Fe 2Àx O 4 (0.0 # x # 0.12) samples by calcining oxalates in air.…”

“…(21) [62,64]: (21) To determine the squareness ratio (S), Eq. (22) was employed [65,14]: (22) The evaluated values of the magnetocrystalline anisotropy constant (K eff ) and S are given in Table VIII. For all samples S < 0.5, which indicates uniaxial anisotropy contribution in the prepared Note that FIG.…”

“…Rare-Earth doping significantly alters the nucleation and growth of nanoferrites, which facilitate magnetic spin orientation [2,14]. It is known that the magnetic behavior of spinel ferrite compounds is mostly due to the interaction between the iron atoms [14].…”

“…Rare-Earth doping significantly alters the nucleation and growth of nanoferrites, which facilitate magnetic spin orientation [2,14]. It is known that the magnetic behavior of spinel ferrite compounds is mostly due to the interaction between the iron atoms [14]. Rare-Earth ions are more favorable to enter in octahedral sites of the spinel structure; this causes 4f-3d interactions that promotes structural distortion, lattice strain and changes in saturation magnetization [14].…”

Structural, Morphological, and Optomagnetic Properties of La/Cu/Cu-Mn Ferrite Ternary Nanocomposites

“…Currently, scientific researchers have shifted their attention to developing ferrite composites materials at the nano-level. [11][12][13][14][15] Thus, nanocomposites are a novel material and their importance is increasing day by day due to their noticeable properties arising from the synergism of their base and added material. In addition, development of nanocomposites has no restriction on the mixture of materials, which leads to inventive and intensive research.…”
