The magnetic properties of nano-crystalline CoMxFe2 xO4 (where M=Gd and Pr and x 1⁄4 0; 0.1 and 0.2) powders prepared by a citrate precursor technique have been studied by using vibrating sample magnetometer (VSM). The crystallite sizes of the materials were varied by altering the synthetic conditions and are within the range of a minimum of 6.8 nm and a maximum of 87.5 nm. The materials were c...

Divalent ferrite nano-crystalline materials subjected to shock wave recovery analysis bringing about prolific outcomes have received widespread attention among the scientists due their outstanding contribution that has fueled enrichment of science involving high-pressure ferrites which act as focal-point current research theme. On those lines, we intend provide Raman spectroscopic and electroch...

Ferrimagnetic insulators have gained much attention as material platforms with efficient magnetization dynamics. To date, epitaxial iron garnet thin films are the most widely used materials in emerging field of “insulator spintronics.” However, further advances this require overcoming disadvantages garnets—e.g., their complex structure, high growth temperature, incompatibility other crystalline...

The results of studies the properties co-deposition magnetic nanoparticles (MNPs) Co 1-x Zn x Fe 2 O 4 spinel ferrites synthesized (at x=0.0; 0.1; 0.2; 0.4; 0.6) in order to synthesize particles for biomedical applications. X-ray diffraction (XRD), raman spectra, measurements and Mossbauer spectroscopy (MS) were used study MNPs. It was found that MNPs are single-phase. According XRD measurement...

Thermochemical and compressibility data are used to calculate the approximate pressures and temperatures required for the reaction of clinoenstatite to Mg•SiO• (spinel or olivine) or to periclase and stishovite, the reaction of forsteritc to Mg•SiO• (spinel) or periclase and stishovite, and the breakdown of Mg•SiO• (spinel) to periclase and stishovite. The calculated reaction lines for Mg•SiO• ...

Geologists usually deal with rocks that are up to several thousand million years old. They try to reconstruct the tectonic settings where these rocks were formed and the history of events that affected them through the geological time. The spinel group minerals provide useful information regarding the geological environment in which the host rocks were formed. They constitute excellent indicato...

Present work reports the synthesis of RE3+ (La3+, and Ce3+) Co2+ co-doped Zn0.75Cu0.25Fe2O4 samples powder using sol-gel auto combustion process. Rietveld refinement established spinel matrix with space group (F d -3 m) suggests that uniform distribution cations at tetrahedral octahedral lattice sites. The comparative study crystallite size (D) was found Scherrer's relation, plot, Williamson-Ha...
