Study of Electrical and Magnetic Properties of Praseodymium Samarium Doped Novel Magnesium Ferrite

Abstract

The Praseodymium, Samarium doped novel Magnesium ferrite (Mg Pr x Sm y Fe 2-x-y O 4 ) was prepared by sol gel route and sintered in a microwave furnace. The nano size, structure and composition of Pr and Sm doped Magnesium ferrite ceramics was analyzed by X-ray diffraction and confirmed by SEM monographs. The elemental conformation was done by EDAX. The hysteresis property of this material was conformed through its hysteresis curves. The permeability of this material was calculated by using the magnetic saturation obtained from the hysteresis curves.The electrical measurements have been performed to determine the dielectric constant ( r ), dielectric loss ( r ) and loss tangent in the frequency range of 20KHz -20MHz. It is also found that the permittivity of these nano materials is being reduced with the increase in frequency.

The Analysis of Cu1-xNixFe2O4 Nanoferrites' Structural, Morphological, Optical, and Magnetic Characteristics

“…The v1 band, linked predominantly to intrinsic stretching vibrations of metal and oxygen atoms at the tetrahedral site, commonly manifests within 542 to 555 cm-1 (Mtetra-O). Conversely, the lowest band 2 typically corresponds to stretching vibrations of the metal at the octahedral site, falling between 454 and 470 cm-1 (Mocta-O) [45]. Our FTIR spectra align with earlier investigations [23,50].…”

Effect of Cu2+/Ce3+ substituted on synthesis, structural, morphological, magnetic, DC electrical resistivity and dielectric properties of Cobalt nano ferrites

“…The energy of activation is an electron's energy to bounces from one particle to a neighbouring particle. The energy gap between the valence band's top and the conduction band's bottom in pure semiconductors measures the activation energy [57]. The activation energy is found to increment from 0.35 to 0.49 eV, followed by an increase in activation with increments in Cu 2+ /Ce 3+ substitution.…”
