Magnetic tight binding and the iron-chromium enthalpy anomaly

Magnetic Cluster Expansion Model for High-Temperature Magnetic Properties of Iron and Iron-Chromium alloys

Adsorption and Desorption Process of Chromium Ions Using Magnetic Iron Oxide Nanoparticles and Its Relevant Mechanism

In this study adsorption of Cr(VI) from aqueous solution by Fe3O4 nanoparticles was investigated. Desorption process and recovery of nanoparticles using different solutions were then carried out, and it was observed that NaOH (0.5M) can remove 90% of adsorbed chromium ions. Following the completion of adsorption/ desorption cycles, it was determined that nanoparticles have still had a high abil...

Manganese and Iron Binding to Human Transferrin

The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

Magnetic properties of iron cluster/chromium matrix nanocomposites

A custom-designed apparatus was used for the fine-tuned co-deposition of preformed Fe clusters into antiferromagnetic Cr matrices. Three series of samples with precisely defined cluster sizes, with accuracy to a few atoms, and controlled concentrations were fabricated, followed by a complete characterization of structure and magnetic performance. Relevant magnetic characteristics, reflecting th...

Iron� High Magnetic Field Behavior of Impurities Chromium� In

THE PRESENCE of small amounts of iron in chromium metal results in a lowering of the Neel temperature along with other anomalous diagram[l, changes in the phase r 1 , 2]. Suscepti­[I] N eel bility measurements 1 below the tem­perature show that the iron sites have associ­ated with them localized magnetic moments of about 1·4f.LIJ I· per iron atom and that the iron moments remain paramagnetic do...
