Аннотация: Organic-based spintronics is one of the most fast-developing fields in nanoelectronics. Buckminsterfullerene-based composites are widely investigated due to its unique properties and there is a number of studies concerned with its interfaces with various types of substrates. Ferromagnetic surfaces are of a particular interest for potential spintronics applications. Based on the data reported in literature, we suppose that there are more than one stable structure in C60/Fe(001) composite system. Here we investigate different possible adsorption sites of C60 molecule and reveal the possibility of their coexistence and its influence on the composite properties. © 2016 Elsevier B.V.

Ключевые слова (''Своб.индексиров.''): transition metal trihalides--magnetic properties--thermoelectric--conversion--density functional theory
Аннотация: Using DFT GGA calculations, electronic structure and magnetic properties of wide family of transition metal trihalides (TMHal3) (Zr, Ti and Nb iodides, Mo, Ru, Ti and Zr bromides and Ti or Zr chlorides) are investigated. These structures consist of transition metal atoms chains surrounded by halides atoms. Chains are connected to each other by weak interactions. All TMHal3 compounds were found to be conductive along chain axis except of MoBr3 which is indirect gap semiconductor. It was shown that NbI3 and MoBr3 have large magnetic moments on metal atoms (1.17 and 1.81 µB, respectively) but other TMHal3 materials have small or zero magnetic moments. For all structures ferromagnetic and anti-ferromagnetic phases have almost the same energies. The causes of these properties are debated.
