Dipolar Magnetic Anisotropy in Some Uniaxial Hexagonal Ferrites
نویسندگان
چکیده
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 in hexagonal ferrites is mainly due to the dipolar magnetic contribution.

Dipolar Energy Anisotropy in Hexagonal Ferrites
The dipolar energy contribution to the anisotropy of M, Wand Y-type hexagonal fenites is examined. The geometrical coeff~cients kij are given, so that a calculation for any hexaferrite with the same structure can be effected. Differences in the results of previous works are explained as due to a simplifying assumption, the validity of which is restricted. The ambiguity regarding dipolar energy ...

Theoretical estimates of phase shifter performance as a function of material parameters are presented by examining the results obtained from the small perturbation model used by Button and Lax and from the fully ierrite loaded, parallel plane waveguide model used by Suhl «And Walker. The extension of Suhi's theory on nonlinear effects at high power by Fletcher and Silence is applied to relate t...

We have studied the integration of Ni-Cu-Zn ferrite spinels as well as substituted hexagonal Co2Y-and M-type ferrites into LTCC (Low Temperature Ceramic Co-firing) modules. The cofiring behavior and the magnetic properties of these materials were investigated and evaluated for multilayer applications. Ni-Cu-Zn ferrites exhibit permeabilities of μ = 300 – 500 for operating frequencies in the MHz...
متن کاملMillimeter wave notch filters based on ferromagnetic resonance in hexagonal barium ferrites
A hexagonal ferrite-based millimeter wave notch filter was demonstrated. The filter consists of an M-type BaFe12O19 BaM slab sitting on top of a stripline. The band-stop filtering response originates from the ferromagnetic resonance absorption in the BaM slab. The BaM slab has an in-plane uniaxial anisotropy field of 17 kOe. This anisotropy field facilitates the operation of the filter beyond 5...
متن کاملMagnetic and structural characterization of nanosized BaCo_xZn_2-xFe_16O_27 hexaferrite in the vicinity of spin reorientation transition
Numerous applications of hexagonal ferrites are related to their easy axis or easy plane magnetocrystalline anisotropy configurations. Certain W-type ferrites undergo spin reorientation transitions (SRT) between different anisotropy states on magnetic field or temperature variation. The transition point can be tuned by modifying the chemical composition, which suggests a potential application o...
