Structural and electrical properties of nickel cadmium ferrites prepared through self-propagating auto combustion method

Structural, electrical and magnetic properties of cadmium substituted nickel–copper ferrites

“…where e is the charge of electron, is the resistivity, n is the charge carrier concentration and which is calculated using the following relation [14] …”

“…The lattice parameter increases due to the increase of cadmium content in the ferrites because of its higher ionic radius compared to other ions in the ferrites. Several researchers have studied the structural, electrical and magnetic properties of substituted ferrites like Ni-Co-Cu [1], Ni-Cd-Zn [12], Ni-Cd [11,[13][14][15], Ni-Cu [16], Mg-Cd [17] and Ni-Mn-Mg [18] mixed ferrites by different methods. However, the literature survey on Ni-Cd-Cu ferrites indicates that not much work has been done on these ferrites.…”

Dielectric Response of Nix Zn1-x Al Fe O4 Nanoferrites

“…Ni-Zn ferrite is a soft magnetic and an important ceramic material which has enormous applications in various fields like electric, magnetic, electronics, microwave devices, catalysts, transformers cores, power conversions, high frequency applications in telecommunications, magnetically control drug delivery system, for multilayer inductor applications, etc [1][2][3][4][5][6][7]. The nanoferrite properties can be easily adjustable, controllable to a great extent by choosing proper preparation methods and suitable doping with divalent, trivalent and rare earth ions [8][9][10]. Different cation substitutions can distribute into the voids of the parent crystal structure and can alter many properties of nanoferrites like DC resistivity, mobility of the charge, desire magnetization, activation energy, Curie temperature and dielectric losses.…”

Cation distribution investigation and characterizations of Ni1−xCdxFe2O4 nanoparticles synthesized by citrate gel process

“…The addition of Cd 2+ is expected to increase number of pores, vacancies and the scattering centers for the electric charge carriers. A pore is a sort of void or gap which breaks the magnetic circuit between the grains and acts as obstacle to the domain wall rotation giving rise to increase in resistance of the sample [19]. The selective area electron diffraction (SAED) analyses of the typical sample x = 0.2 is shown in Fig.…”
