The Transition from Paramagnetic to Ferromagnetic States as Influenced by Evolving Microstructure of Ni0.5Zn0.5Fe2O4

Structural and Magnetic Properties of Hydrothermal Spinel Ni0.4Zn0.6Fe2O4 Ferrites

“…In addition, also found is that the particle size roughly increased with the increase of sintering temperatures. Our SEM result is consistent with the previous report 1 . To further interpret the phase composition, XRF, TGA-DTA and FTIR analysis were used to confirm the results of XRD.…”

“…Spinel (Ni,Zn)Fe 2 O 4 (NZFO) ferrite is one of the most extensively studied soft magnetic materials for their fine chemical stability and distinct magnetic and electrical properties [1][2][3][4][5] . Various techniques have been used to synthesize fine NZFO particles with some novel properties compared with corresponding bulks.…”

Sintering Temperature Dependence of Evolving Morphologies and Magnetic Properties of Ni0.5Zn0.5Fe2O4 Synthesized via Mechanical alloying

“…We have reported the magnetic phase transition as influenced by evolving microstructure of the sample in Ref. [14] and within this report; a higher precision of sample sintering was carried out within the region of 800°C to 1000°C believed to be the transition point of the microstructure-magnetic property. The goal of this work is to study the effects of sintering temperature of Ni 0.5 Zn 0.5 Fe 2 O 4 synthesized via mechanical alloying and to observe the parallel evolving morphologies and magnetic properties of this material.…”

“…Further details of the mechanically alloyed and as-prepared powders has been studied and reported in Ref. [15]. The alloyed powder was then divided into nine samples and was then uniaxially pressed into toroidal shape of 20-mm outer diameter and 9-mm inner diameter with 2 wt% of PVA as binder under a pressure of 56.34 MPa.…”

Controlled synthesis and microwave absorption properties of Ni0.6Zn0.4Fe2O4/PANI composite via an in-situ polymerization process

“…However, the microwave absorption properties achieved by single nickel zinc ferrites to date has been far below what is expected, because the materials are suffered from poor stability and high density [10,11]. Previous efforts have focused on constructing nickel zinc ferrites composites with polymers [12], carbon-based materials [13], transition metal oxides [14] etc.…”
