Magnetic properties of as-deposited Fe–Al–O alloy films

Abstract

The magnetic and structural properties of as-sputtered nanocrystalline Fe–Al–O films, fabricated by a magnetron sputtering apparatus, are investigated as a function of the sputtering input power and the contents of Al and oxygen. A nanocrystalline Fe88.5Al3.5O8.0 film is found to have 4πMs of 18.2 kG, Hc of 0.6 Oe, μeff of 4600 up to 100 MHz. These excellent soft magnetic properties and high frequency characteristics result from nanocrystalline structure, high electrical resistivity, and moderate anisotropy field. These values are sufficient to apply to a high-density recording head.

Electrical Properties of Sol-Gel Derived PbLaZrTiOx Capacitors with Nonnoble Metal Oxide Top Electrodes

“…Figure 6 shows the fatigue endurance properties after 10V, 100 us width and 1 ms interval cycles. This fatigue behavior was caused by function of oxide electrodes as a sink for oxygen vacancies 5,10) . In previous study, it is clearly revealed that oxide electrodes can improve the film fatigue resistance 11,12) When the cycling voltage was 10 V, PLZT capacitors with Pt top electrodes showed significant degradation of polarization after 10 4 cycles.…”

Properties of (Ni-P)-SiO2 (Nanometer) Electroless Composite Coating on PET Fabrics

“…Among the various metallization processes, electroless metal plating is probably a preferred way to produce metal-coated fabrics due to the attractable advantages such as uniformity of coverage, excellent conductivity, the possibility of metallizing nonconductors, and flexibility [1]. In the previous investigation, the properties of electromagnetic shielding of electroless Ni-, Cu-and Ag-plated fabrics were extensively studied [2][3][4][5].…”
