Fabrication of Soft Magnetic Fe-based Nanoalloy

Fabrication and magnetic properties of Fe–Pd nanowire arrays

Ordered 20 nm Fe–Pd nanowire arrays with different compositions have been fabricated by alternating current electrodeposition into nanoporous anodic alumina. The structural and magnetic properties of the arrays were investigated by transmission electron microscopy (TEM), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). When Fe content is lower than 46 at.%, Fe–Pd alloy phase wit...

High-Frequency Behavior and Damping of Fe–Co–N-Based High-Saturation Soft Magnetic Films

Magnetization dynamics measurements at subnanosecond time scale have been performed on Fe–Co–N high-saturation soft magnetic films with Permalloy nanolayer seeds and having a saturation magnetization of 1.9 MA/m (1900 emu/cm). The damping parameter varies from 0.011 to 0.018, depending on applied bias field. The peak frequencies of the imaginary permeability spectra and the zero-crossing freque...

HSQ-Based Fabrication of Magnetic Nanopillars

Hydrogen silsesquioxane (HSQ) has been used as e-beam resist and ion milling mask in the fabrication of spin valve devices. The excellent performance of HSQ in patterning nanometer size features and corresponding procedures such as chemical mechanical polishing (CMP) make the HSQ-based process a reliable and economic way to make nanomagnetic devices.

Fabrication of Fe-Based Diamond Composites by Pressureless Infiltration

A metal-based matrix is usually used for the fabrication of diamond bits in order to achieve favorable properties and easy processing. In the effort to reduce the cost and to attain the desired bit properties, researchers have brought more attention to diamond composites. In this paper, Fe-based impregnated diamond composites for drill bits were fabricated by using a pressureless infiltration s...

Effect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets

Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...
