Investigation on structure, thermodynamic and multifunctional properties of Ni–Zn–Co ferrite for Gd³⁺ substitution

Abstract

This study presents a modification of structure-dependent elastic, thermodynamic, magnetic, transport and magneto-dielectric properties of a Ni–Zn–Co ferrite tailored by Gd3+ substitution at the B-site replacing Fe3+ ions.

Correlation among the structural, electric and magnetic properties of Al3+ substituted Ni–Zn–Co ferrites

“…Oxides were hand-milled carefully for 6 h by using an agate mortar and pestle. 25 The homogeneous mixtures were mixed with deionized (DI) water and compressed (5 kN) into circular tablets. The tablets were pre-sintered at 800 °C for 4 h at a heating rate of 5 °C min −1 .…”

Graphene nanoplatelets (GNPs): a source to bring change in the properties of Co–Ni–Gd-ferrite/GNP nanocomposites

“…The same trend is found when GNPs are added to CNGF but with less diversity. 20 These reveal that lesser ferrite particles could get into the honeycomb or hexagonal structures of GNP, causing a rise in the density of functional groups that act as charge carriers. Therefore, the conductivity of graphene remains supreme, and the resistivity of the composites deteriorates with different concentrations of GNP, as shown in Fig.…”

“…Due to substitution with gadolinium, they found changes in the structural properties, as well as electrical properties. 20 It is worth mentioning that the content of graphene plays an important, leading role in defining the dielectric behavior of carbon materials along with their magnetic anisotropy. This subsequently would impact the microwave weakening behavior.…”

Research on the physical properties of LiMn0.5Fe2O4 spinel ferrites by the combination of optical, magnetic, and dielectric behaviors

“…Research in nanotechnology is a fast-growing field at the forefront of physics and is attracting special interest from the scientific community. 1 Multifunctional materials, in particular, are investigated for their advantageous properties that are combined in one smart compound. 2,3 A broad range of intelligent materials have been proposed and among them, ferrites have drawn significant attention and are deemed to be promoter hosts due to their extremely prominent features.…”
