High-performance permanent magnets for energy-related applications require a high energy product (BH)max. It has been proposed that the two-phase materials exchange-coupled between magnetically hard and soft phases may greatly enhance the energy products.[1,2] More recently, self-assembly of two-component with hard magnetic phase FePt and soft magnetic phase Fe3Pt nanocomposites has successfully enhanced...
Magnetic nanostructures have attracted a great deal of attention during the last decade because of their prospective applications not only in microwave absorption, high density recording media, and biosensor applications but also in functional micro and nanodevices [1-4]. Recently, significant investigations have been motivated to get excess of 1Tbit/in2 in magnetic storage devices but at smaller...
A microfluidic structure to measure water vapor permeation through thin film Parylene C was successfully fabricated and tested. Chips were re-tested multiple times with consistent results. These chips were tested at 20degC, 30%RH and measured WVTR data that matched equivalent wet-cup/beaker tests, showing that these devices are indeed functional and can be used to measure WVTR with repeatable reliability...
Pulse stress tests on magnetic tunnel junctions (MTJs) with a MgO barrier (~5.5 Aring) were conducted. Both the E (McPherson and Mogul, 1998) and 1/E (Chen and Holland, 1985; Schuegraf and Hu, 1994) models can describe the intrinsic breakdown behavior of this ultrathin barrier within the range of voltages studied. While constant voltage stress (CVS) and ramped voltage pulse stress (RVPS) testing yield...
