Origin of dead magnetic Fe overlayers on V„110..

چکیده
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 thickness. However, if alloying is present at the interface, a strong decrease in the Fe magnetization is found. We discuss the different magnetic configurations and the possible mechanisms that can produce the observed magnetically dead Fe layers.

Suppression of ferromagnetic order of Fe overlayers on the Rh„001... surface
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 tetragona...
متن کاملBromine and Iodine Adsorption on an Fe ( 100 ) Surface
We studied bromine and iodine adsorption on an Fe(100) surface in the temperature range of 110 K to 700 K. In this communication we compare core-level binding energies of dissociatively and molecularly adsorbed halogen species as a function of coverage. Our valence band photoemission data suggest that bromine and iodine adsorption at 300 K is always dissociative. At 110 K, initial dissociative ...
متن کاملAn Augmented Space Recursion Study of the Electronic Structure of Rough Epitaxial Overlayers
In this communication we propose the use of the Augmented Space Recursion as an ideal methodology for the study of electronic and magnetic structures of rough surfaces, interfaces and overlayers. The method can take into account roughness, short-ranged clustering effects, surface dilatation and interdiffusion. We illustrate our method by an application of Fe overlayer on Ag (100) surface.
متن کاملMagnetic profiles and coupling in Fe/Cr(110) superlattices
In epitaxial Fe/Cr superlattices the coupling between the Fe layers oscillates between antiferromagnetic (AFM) and ferromagnetic as a function of the Cr layer thickness tCr. The period of the oscillation is the same for superlattices grown with (211) and (100) orientations. We measured the coupling of Fe/Cr(110) superlattices consisting of three identical Fe layers. The magnetization curves wer...
