Magnetic and structural studies of the Mn-doped Mg–Zn ferrite nanoparticles synthesized by the glycine nitrate process

Structural and FTIR Spectroscopic Studies of Mg-Zn Ferrite Nanoparticles Synthesized by Co-Precipitation Technique

“…These secondary phases were also observed in other ferrites at low annealing temperatures [10,11]. The diffraction planes are analyzed with powder software and the planes are indexed as (220), (311), (400), (422), (511) and (440) which are well matched with the earlier reports [12]. The broadening and low intensity of diffraction peaks is attributed to presence of ultrafine particles in the samples.…”

Mössbauer Spectroscopy, Structural and Magnetic Studies of Zn2+ Substituted Magnesium Ferrite Nanomaterials Prepared by Sol‐Gel Method

“…Table 1 indicates that the lattice constant increases with the increasing substitution of Zn 2+ ions. The increase in lattice parameter is probably due to replacement of smaller Mg 2+ ions (0.72Å) by larger Zn 2+ ions (0.74Å) [8,9]. The X-ray density was calculated using the relation [4, 10, 11]:…”

“…And the coercivity tends to decrease with Zn content increasing. The magnetic coercivity of the particles depends significantly on their magnetocrystalline anisotropy, microstrain, interparticle interaction, temperature, size, and shape [9,26,27]. However the Zn 2+ and Mg 2+ ions have no unpaired electrons and lead to zero total electron spin.…”

Microwave Assisted Synthesis and Characterization of CoxZn1−xCr0.5Fe0.5O4 Nanoparticles

“…3c). It is may be due to the surface temperature that affects the molecular concentration and makes the tiny crystal to grow at the surface of the crystal, thereby increasing the molecular concentration at the crystal surface, which in turn increases the grain growth [16,[32][33][34]. The differences in the results reported in the literature (lattice parameters and crystallites size of the ferrites) depend on the type of preparation methods, reaction condition (time, temperature etc.…”
