Mechanical properties of soft magnetostrictive FeCo-based thin films is one the critical along with their magnetic properties. To fully exploit potential in magnetic-microelectromechanical (MagMEMs) application, elastic and inelastic as well strength need to be considered. This paper presents mechanical FeCoCr at varied Cr concentrations from 2.6 9.6 at% fabricated by RF Sputtering. Nanoindenta...
FeCo-graphitic carbon shell nanocrystals are a novel MRI contrast agent with unprecedented high per-metal-atom-basis relaxivity (r(1) = 97 mM(-1) sec(-1), r(2) = 400 mM(-1) sec(-1)) and multifunctional capabilities. While the conventional gadolinium-based contrast-enhanced angiographic magnetic MRI has proven useful for diagnosis of vascular diseases, its short circulation time and relatively l...
The sulphhydryl environment in various mixed-metal hybrid hemoglobins, viz. α2(Cu)β2(FeCO), α2(FeCO)-β2(Cu), α2(Cu)-β2(Ni), α2(Ni)-β2(Cu), was studied by reacting them with the sulphhydryl reagent, 4,4′-dithiodipyridine (4-PDS). The reactivity was compared with that of HbCO, NiHb and CuHb. It is found that there exists a correlation between conformational change and metal ion environment, not o...
Introduction: We have recently developed and tested new FeCo/graphitic carbonshell (FeCo/GC) nanocrystals with interesting properties for MRI. The following summarizes these properties (advantages): (1) highest magnetization [1] among all magnetic materials, allowing a lower dosage for high contrast; (2) non-toxic due to encapsulating graphite carbon shell; (3) superparamagnetic up to 20 nm or ...
Spin injection from Fe(001) and (Ga,Mn)As(001) into n-GaAs(001) was investigated using a method which provides two-dimensional cross-sectional images of the spin polarization in GaAs. While the distribution of the spin polarization below the injecting contact is nearly uniform for (Ga,Mn)As, a strong confinement near the contact edge is observed for Fe and FeCo. The spin polarization in GaAs ch...

The thermal stability of siderite (FeCO(3)) was studied by two independent methods in which the oxygen fugacity of the gas phase was controlled by equilibration with graphite. Both series of experiments indicate that siderite decomposes stably to magnetite + graphite between 455 degrees and 465 degrees C at 500 to 2000 bars PCO2 + P(CO).
