Magnetic Characteristic Changes in Polished Ferrites

Dipolar Magnetic Anisotropy in Some Uniaxial Hexagonal Ferrites

Calculations for the magnetic dipolar contribution to the magnetic anisotropy of BaFeizOie and LaFeiiZnOie M-type and BaFerMn2Oil A-type hexagonal ferrites have been made. Our calculations take into account all the magnetic moments existing within a sphere with a radius of 118 1, from which good eonvergenee is reached. The results for there ferrite# suggest that the strong magnetic enisotropy i...

Enhancement of the Magnetic Properties for Co-Mn-Zn Ferrites

Aluminum substituted cobalt manganese zinc ferrite nanoparticles Co0.425Mn0.425Zn0.150AlxFe2-xO4 (from x= 0.0 to 0.15 with step 0.025) have been synthesized by chemical co-precipitation route. X-ray diffraction (XRD) and infrared spectroscopy (FTIR) revealed that the obtained powders have a single phase of cubic spinel structure. The crystallite sizes calculated from XRD data have been confirme...

Site-Specified Magnetic States in Ferrites Probed by Magnetic Circular X-Ray Dichroism

To study magnetic states in ferrimagnetic Fe-oxides, we have measured magnetic circular x-ray dichroism at K-edge of Id-transition metal. The observed dichroic signals are separately assigned to the contribution come from 3d-cation in tetrahedral or octahedral sites. We discuss the magnetic states of 3d-metal ion in terms of local enviroment. Magnetic circular x-ray dichroism (MCXD is a powerfu...
