Wide Bandwidth Microwave Absorbers of Ferrite-Rubber Composites with Square-Rod Structure

MATEC Web of Conferences, 2016
As one way of shape control for the wide bandwidth in microwave absorbers, a square-rod structure of ferrite composite is proposed. Microwave absorbance of the square-rod absorber is analyzed by the transmission line approximation which provides the ...

Structural and magnetic properties of nanocrystalline BaFe12O19 synthesized by microwave-hydrothermal method [PDF]

, 2012
Nanocrystalline BaFe12O19 powders were prepared by microwave-hydrothermal method at 200 °C/45 min. The as-synthesized powders were characterized by using X-ray diffraction (XRD), thermogravimetry (TG) and differential thermal analysis (DTA).

Investigation of magnetic and structural properties of copper substituted barium ferrite powder particles via co-precipitation method

Results in Physics, 2016
In this paper, it is proposed to synthesize copper-doped barium ferrite (BaCuxFe12−xO19) using co-precipitation technique at different ratios in order to increase the coercivity value which in turn increases the magnetic storage capacity of the copper ...

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.
