Magnetic Property and Evaluation of MnZn-Ferrite Fine Particles in Langmuir Blodgett Film

چکیده
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 picture of the magnetic viscosity which is realized in reentrant spin glass materials.

Infrared Properties and Terahertz Wave Modulation of Graphene/MnZn Ferrite/p-Si Heterojunctions
MnZn ferrite thin films were deposited on p-Si substrate and used as the dielectric layer in the graphene field effect transistor for infrared and terahertz device applications. The conditions for MnZn ferrite thin film deposition were optimized before device fabrication. The infrared properties and terahertz wave modulation were studied at different gate voltage. The resistive and magnetic MnZ...
متن کاملCore-shell-structured magnetic ternary nanocubes.
We report a novel core-shell-structured ternary nanocube of MnZn ferrite synthesized by controlling the reaction temperature and composition in the absence of conventionally used reducing agents. The highly monodispersed core-shell structure consists of an Fe(3)O(4) core and an MnZn Ferrite shell. The observation of a Moiré pattern indicates that the core and the shell are two highly crystallin...

متن کاملLangmuir Blodgett films of arachidic acid and N4 molecules: characterization and use in homeotropic alignment of N4
We study the behavior of a mixed Langmuir monolayer consisting of a fatty acid and a nematic liquid crystal. We demonstrate that the mixed monolayer successfully transfers as a Langmuir-Blodgett film and characterize the transferred film using UV spectroscopy. An important application of Langmuir-Blodgett films is in the alignment of liquid crystals for electro-optical applications, such as dis...
