Barium Hexaferrite Thick Films for Microwave Absorbers and Circulators
Barium hexaferrite (BaHF) with the chemical formula BaFe12O19 is a hard magnetic material and has high magnetic anisotropy field (MAF), 17 kOe. The easy direction of magnetization corresponds to the crystallographic c-axis and BaHF particles orient in this direction when are exposed to an external magnetic field. Because of the high MAF, a ferromagnetic resonant frequency appears from 45 to 50 ...

متن کاملMultiferroics and magnetoelectrics: thin films and nanostructures
Multiferroic materials, or materials that simultaneously possess two or more ferroic order parameters, have returned to the forefront of materials research. Driven by the desire to achieve new functionalities—such as electrical control of ferromagnetism at room temperature—researchers have undertaken a concerted effort to identify and understand the complexities of multiferroic materials. The a...
متن کاملSurfactant-Assisted Electrodeposition of CoFe-Barium Hexaferrite Nanocomposite Thin Films
The influences of anionic sodium dodecylsulfate (SDS) and cationic Hexadecyltrimethylammonium bromide (HTAB) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited CoFe-BaFe12O19 composite thin films were studied. Sulphate bathes with natural pH containing 0 to 2 g/L surfactants were used for electroplating at room temperature. Field emissi...
متن کاملThermal conductivity in nanostructured films: from single cellulose nanocrystals to bulk films.
We achieved a multiscale description of the thermal conductivity of cellulose nanocrystals (CNCs) from single CNCs (∼0.72-5.7 W m(-1) K(-1)) to their organized nanostructured films (∼0.22-0.53 W m(-1) K(-1)) using experimental evidence and molecular dynamics (MD) simulation. The ratio of the approximate phonon mean free path (∼1.7-5.3 nm) to the lateral dimension of a single CNC (∼5-20 nm) sugg...
