Temperature Dependence of Cation Distribution and Oxidation State in Magnetic Mn-Fe Ferrite Nanocrystals
The magnetic properties of spinel nanoparticles are determined by crystal chemistry issues such as cation distribution and oxidation states. The cation distribution and oxidation state of Mn-Fe spinel nanoparticles have been systematically studied at various temperatures by using neutron diffraction and electron energy loss spectroscopy, respectively. The Mn-Fe spinel nanoparticles prepared by ...
متن کاملTemperature dependence of magnetic anisotropy constant in manganese ferrite nanoparticles at low temperature
The temperature dependence of the effective magnetic anisotropy constant, K(T), of MnFe2O4 nanoparticles is obtained based on superconducting quantum interference device magnetometry measurements. The variation of the blocking temperature, TB, as a function of particle radius, r, is first determined by associating the particle size distribution and the anisotropy energy barrier distribution ded...
متن کاملStudy on The Influence of Crystal Structure and Grain Size on Dielectric Properties of Manganese Ferrite (MnFe2O4) Nanoparticles
Manganese ferrite (MnFe2O4) has been successfully synthesized by using coprecipitation methods with a various particles size of 13.1, 13.8, 16.2, 18.1, and 18.4 nm. Analysis of crystal structure properties which has been carried out by using XRD (X-Ray Diffraction) method revealed that all samples belong to cubic spinel structure. The measurement used computerized impedance spectroscopy system ...
متن کاملFormation and cation distribution in supported manganese ferrite nanoparticles: an X-ray absorption study.
Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) techniques at both Fe and Mn K-edges were used to investigate the formation of MnFe(2)O(4) nanoparticles embedded in a silica aerogel matrix as a function of calcination temperature (at 450, 750 and 900 degrees C). Up to 450 degrees C, two separated highly-disordered phases of iron and manganese ar...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
