“…[1][2][3][4][5][6][7][8] It presents a cubic structure with space group Ia3d, and each unit cell contains eight Y 3 Fe 5 O 12 molecules. [9][10][11] The corresponding ion distribution structure can be represented by the garnet formula of {Y 3 [octahedral], and 24d (tetrahedral) sites, respectively.…”

Y 3Àx La x Fe 5 O 12 (x ¼ 0-0.5) ceramics with garnet structure are prepared by the solid state reaction method and their structural, magnetic, and magnetodielectric properties are investigated systematically. La 3þ substitution leads to lattice expansion and possible ion transposition, which oppositely affect the variation of Fe 2þ concentration. As a result, both the saturation magnetization and the intrinsic magnetodielectric effect first increase and then decrease with the increase of La concentration. More interestingly, room temperature large magnetodielectric coefficient of about À5% is obtained at 10 6 Hz and 0.9 T for Y 2.7 La 0.3 Fe 5 O 12 ceramics. This study provides a feasible alternative method for modulating the saturation magnetization and the magnetodielectric effect of Y 3 Fe 5 O 12 -based materials. V C 2015 AIP Publishing LLC.

“…In addition, the synthesis Sm 3þ eGd 3þ ion doped at Fe 3þ site in MneZn ferrites have not yet been reported in the literature. There are many conventional synthesis methods to synthesize rare earth ion doped MneZn ferrites such as chemical co-precipitation method [7e9], solid state [10], hydrothermal synthesis [11], microwave hydrothermal (MÀH) [12], solegel [13,14] and solution combustion [15,16]. Among all, solution combustion route is simple and economically feasible [17] to obtain nanosized Sm 3þ eGd 3þ co doped MneZn ferrite particles at its assynthesized form without need of post heat treatment.…”

a b s t r a c tNanocrystalline Mn 0.4 Zn 0.6 Sm x Gd y Fe 2-(xþy) O 4 (x ¼ y ¼ 0.01, 0.02, 0.03, 0.04 and 0.05) were synthesized by combustion route. The detailed structural studies were carried out through X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM). The results confirms the formation of mixed spine phase with cubic structure due to the distortion created with co-dopants substitution at Fe site in MneZn ferrite lattice. Further, the crystallite size increases with an increase of Sm 3þ eGd 3þ ions concentration while lattice parameter and lattice strain decreases. Furthermore, the effect of SmeGd co-doping in MneZn ferrite on the room temperature electrical (dielectric studies) studies were carried out in the wide frequency range 1 GHze5 GHz. The magnetic studies were carried out using vibrating sample magnetometer (VSM) under applied magnetic field of 1.5T and also room temperature electron paramagnetic resonance (EPR) spectra's were recorded. From the results of dielectric studies, it shows that the real and imaginary part of permittivities are increasing with variation of Gd 3þ and Sm 3þ concentration. The magnetic studies reveal the decrease of remnant, saturation magnetization and coercivity with increasing of Sm 3þ eGd 3þ ion concentration. The g-value, peak-to-peak line width and spin concentration evaluated from EPR spectra correlated with cations occupancy. The electromagnetic properties clearly indicate that these materials are the good candidates which are useful at L and C band frequency.

“…However, the sintering temperature of YIG is far beyond the melting points of most electrodes, for example 961°C for Ag, 1063°C for Au, 1083°C for Cu and 1145°C for Ag-Pd. To overcome these troubles, various wet-chemical methods have been used to synthesize finer and more homogenous YIG powders, such as chemical co-precipitation [6][7][8], sol-gel method [9][10][11][12], sol-gel combustion [13][14][15]. Among them, the sol-gel method has attracted much attention due to the finer and more homogeneous particles produced.…”
