Relation Between Firing Conditions Grain Boundary Structure and Magnetic Properties in Polycrystalline MnZn-Ferrites
The influence of the firing conditions on the nanoscale structure of the grain boundaries and on the magnetic properties of polycrystalline MnZn-ferrites is investigated, on specimens of nearly identical microstructures. High oxygen partial pressures favor accumulation of impurity ions at the triple points. Under appropriate oxygen pressures homogeneous accumulation of impurities along the grai...
متن کاملMagnetic force microscopy studies of the domain structure of CoÕPd multilayers in a magnetic field
We have measured the magnetic domain patterns in Co/Pd multilayers of varying thickness using magnetic force microscopy in the presence of an external magnetic field applied perpendicular to the multilayers. We find that the domain patterns evolution is in qualitative agreement with existing theories for single layer thin films. Our results are in reasonable agreement with a theoretical model o...
متن کاملMagnetic Property and Evaluation of MnZn-Ferrite Fine Particles in Langmuir Blodgett Film
We investigated the magnetic properties of thin film samples with different number of layers stacked by the LB technique. The film samples showed a magnetically complex behavior in low temperature region, which is insufficiently explained by the idea of the homogenous dipole interaction field analogous to the demagnetizing field. The film thickness dependent behavior is discussed in terms of a ...
متن کاملMagnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes
Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...
متن کاملGiant magnetodielectric effect and magnetic field tunable dielectric resonance in spinel MnZn ferrite
The sensitive response of the dielectric permittivity under the application of magnetic fields in Mn0.60Zn0.40Fe2.12O4+ polycrystalline ferrite is presented. A magnetic field of 3.5 kOe induced a giant magnetodielectric MD= H − 0 / 0 response, of 1800% at f =7 MHz, at room temperature. The ferrite exhibits a large magnetic field-induced frequency response of 180 Hz/Oe. We suggest that this effe...
