Structure and intermixing in Fe/Fe(110) and Fe/Ag/Fe(110) multilayers

Surface Science, 1998
Abstract We have previously shown, in UHV–SEM studies of Ag/Fe(110), that Ag(111) islands grow on top of two intermediate monolayers of Ag in the Stranski–Krastanov (SK) mode. In the present work, Fe was deposited on samples consisting of (1–5 ML) annealed Ag layers on Fe(110).

FES cycling

2007
Spinal cord injury (SCI) leads to a partial or complete disruption of motor, sensory, and autonomic nerve pathways below the level of the lesion. In paraplegic patients, functional electrical stimulation (FES) was originally widely considered as a means to restore walking function but this was proved technically very difficult because of the numerous ...

Nanocrystalline Fe and Fe-riched Fe-Ni through electrodeposition

Nanostructured Materials, 1999
Abstract There is a constant need for new softer magnetic materials, especially with high saturation moments. A number of studies have shown that by decreasing the average crystal size of a material below 20 nm, it is possible to reduce its magnetic losses.

Magnetic structure of Fe/Cr/Fe trilayers

Physical Review B, 1993
The magnetic structure of Cr films deposited on single crystal Fe(001)/GaAs(001) substrates is investigated by soft x-ray magnetic circular dichroism (SXMCD) of the L2 and L3 absorption edges. We find that 0.25 ML Cr coverages result in Cr moments aligned with each other and antialigned to the underlying Fe moment direction.

Exchange couplings between two Fe layers in Fe/Al/Fe/Ni-Fe/NiO sandwiches

Journal of Materials Science, 1999
Exchange couplings between two Fe layers have been investigated in polycrystalline Fe/Al/Fe/Ni-Fe/NiO and Fe/Al/Fe/Ni-Fe sandwiches. Linear exchange couplings between the two Fe layers were strong and ferromagnetic when the thickness of the Al spacer was between 0.7 and 2.2 nm.

Fe–Mg Interdiffusion in (Mg,Fe)O

Physics and Chemistry of Minerals, 2005
We have performed a series of interdiffusion experiments on magnesiowustite samples at room pressure, temperatures from 1,320° to 1,400°C, and oxygen fugacities from 10−1.0 Pa to 10−4.3 Pa, using mixed CO/CO2 or H2/CO2 gases. The interdiffusion couples were composed of a single-crystal of MgO lightly pressed against a single-crystal of (Mg1-x

Spectrophotometric Determination of Fe(II), Fe(III), and Total Fe

Journal of Pharmaceutical Sciences, 1971
Abstract The orderly use of two known reactions [Fe(II) with α,α'-dipyridyl and Fe(III) with ascorbic acid] allowed to take place successively in the same aliquot sample solution provides a procedure for the quantitative determination of Fe(II), Fe(III), and total Fe. The procedure is simple, rapid, and sensitive enough to cope with samples containing

2018
Results are presented from magnetic and magnetooptical studies of the magnetic configurations in a three-layer film Fe(30?????)/Si(14?????)/Fe(30?????) in which ferromagnetic and biquadratic exchange between iron layers is observed and which also possesses cubic and uniaxial anisotropy. These studies were done at temperatures of 300 and 10 K.

Zweifach arsenverbrückte CrFe-, MoFe- und WFe-bindungen

Journal of Organometallic Chemistry, 1978
Abstract The reaction of K2Fe(CO)4 with (CO)4 M(AsMe2Cl)2 (M  Cr, Mo, W) gives low yields of the new heterodinuclear complexes (CO)4M-[μ-AsMe2]2-Fe(CO)3 with CrFe, MoFe and WFe bonds.

Ideal FeFeS, FeFeO phase relations and Earth's core

Physics of the Earth and Planetary Interiors, 1989
Liquid-state and solid-state model fits to melting data for Fe, FeS and FeO provide constraints for calculating ideal phase relations in Fe-FeS and Fe-FeO systems in the pressure range corresponding to the Earth's outer core. The liquid-state model fit to the Fe melting data of Williams and Jeanloz places constraints on the temperature and other ...
