Suppression of ferromagnetic order of Fe overlayers on the Rh„001... surface
نویسندگان
چکیده
The magnetic phase of thin Fe overlayers on top of a Rh~001! surface has been probed using the surface magneto-optical Kerr effect. Quite surprisingly, we have found a suppression of ferromagnetic order up to six atomic layers of Fe. Not until Fe coverage reaches above seven layers does a ferromagnetic order start to develop. The suppression of ferromagnetic order is attributed to the tetragonally distorted cubic structure, which has been predicted to favor anitiferromagnetic ordering from our first-principles calculation using the full potential linearized augmented plane-wave method. @S0163-1829~99!12943-6#

Origin of dead magnetic Fe overlayers on V„110..
Recent in situ polarized neutron-reflectometry and magneto-optical Kerr effect measurements have displayed a few magnetically dead Fe layers deposited on V~110!. We have performed ab initio density-functional theory calculations in order to explain the a priori unexpected results. An ideal layer-by-layer growth of Fe on the V~110! surface leads to the ferromagnetic solution for every Fe thickne...
متن کاملRemoval of Methyl Orange from Aqueous Solutions by Ferromagnetic Fe/Ni Nanoparticles
Herein, the removal of methyl orange (MO), a monoazo dye, from aqueous solutions was investigated using bimetallic ferromagnetic Fe/Ni nanoparticles (NPs) with the average particle size of 12-16 nm. The effect of contact time, pH, temperature, and Fe/Ni dosage on dye removal process was investigated. The results showed that 60 mg of Fe/Ni NPs at 25 oC and pH= 1 can remove 99.5% of 50 mg/L dye s...
متن کاملCoexistence of charge and ferromagnetic order in fcc Fe.
Phase coexistence phenomena have been intensively studied in strongly correlated materials where several ordered states simultaneously occur or compete. Material properties critically depend on external parameters and boundary conditions, where tiny changes result in qualitatively different ground states. However, up to date, phase coexistence phenomena have exclusively been reported for comple...
متن کاملStructural and electronic properties of CO molecule adsorbed on the TiO2 supported Au overlayers: Insights from density functional theory computations
We have examined the adsorption behaviors of carbon monoxide (CO) molecule on TiO2 anatase supported Au overlayers. The results of density functional theory (DFT) calculations were used in order to gain insights into the effects of the adsorption of CO molecules on the considered hybrid nanostructures. We have investigated different adsorption geometries of CO over the nanoparticles....
