IPB colloquium by Zeljko Sljivancanin

 IPB colloquium will be held on Tuesday, 21 June 2016 at 12:00 in “Dr. Dragan Popović” library reading room of the Institute of Physics Belgrade. The talk entitled


will be given by Dr. Željko Šljivančanin (Vinča Institute of Nuclear Sciences).

Abstract of the talk:

Atoms deposited on well-defined crystalline surfaces can be used to grow nanostructures with magnetic properties substantially different compared to the bulk samples with the same chemical composition. In addition to this, nonmagnetic adatoms can induce magnetism at surfaces which are nonmagnetic prior to their adsorption. Density functional theory (DFT), combined with experimental methods such as scanning tunneling microscopy (STM) and X-ray absorption spectroscopies are powerful tools for understanding fundamental mechanism governing magnetic properties of low-dimensional structures formed at crystalline surfaces. After a brief introduction into a few simple models of magnetism in solid state physics, we will present results from DFT studies of spin magnetism in selected graphene-based materials [1,2]. Then we will describe magnetic properties of metal adatoms and their nanostructures at metal [3] or oxide surfaces [4].
