High permeability of low loss Mn–Zn ferrite obtained by sintering nanoparticle Mn–Zn ferrite

Effect of Gd3+ doping on magnetic, electric and dielectric properties of MgGdxFe2−xO4 ferrites processed by solid state reaction technique

“…6 shows that the values of initial permeability increases with an increase in Gd 3+ ions concentration. These variations can be explained from the following dependence of i [19] i = M 2 s D m K 1 (10) where D m is the average grain diameter, K 1 is the magnetocrystalline anisotropy constant and M s is the saturation magnetization. As i is proportional to M 2 s , the variation of i with x for Gd 3+ should be affected in a manner similar to that of variation of M 2 s with x.…”

“…For the measurements of initial permeability and relative loss factor (RLF) the toroids were wounds with 55 turns of 32 SWG (Standard Wire Gauge) enameled copper wire. The initial permeability was calculated by using the relation [9,10] …”

Heat treatment effects on microstructure and magnetic properties of Mn–Zn ferrite powders

“…These materials are extensively used as inductors, transformers, antenna rods, loading coils, deflection yokes, choke coils, recording heads, magnetic amplifiers, electromagnetic interference devices (EMI), power transformers and splitters [3,4]. Moreover, Mn-Zn ferrites are very important in biomedicine as magnetic carriers for bioseparation, enzymes and proteins immobilization [5][6][7][8].…”

Structural and Magnetic Properties of Cr-Co Nanoferrite Particles

“…These properties along with its great physical and chemical stabilities make Co-ferrite nano-particles be suitable for many technical applications [4]. Their applications include high frequency devices, memory cores, high density information storage and also in biomedical field [5] [6]. The identification of new materials with enhanced properties or new synthesis techniques to improve the performance of existing materials, along with the cost-effective advantages, is always an interesting matter for researchers.…”
