Supramolecular control of the magnetic anisotropy in two-dimensional high-spin Fe arrays at a metal interface

Klaus Kern, Harald Brune, Pietro Gambardella, Magalí Alejandra Lingenfelder, Sylvain Clair, Sebastian Stepanow, Alexandre Dmitriev

Magnetic atoms at surfaces are a rich model system for solid-state magnetic bits exhibiting either classical(1,2) or quantum(3,4) behaviour. Individual atoms, however, are difficult to arrange in regular patterns(1-5). Moreover, their magnetic properties a ...

Does the Surface Matter? Hydrogen-Bonded Chain Formation of an Oxalic Amide Derivative in a Two- and Three-Dimensional Environment

Klaus Kern, Harald Brune, Uta Schlickum, Sylvain Clair, Marta Canas Ventura

We report on a multi-technique investigation of the supramolecular organisation of N,N-diphenyl oxalic amide under differently dimensioned environments, namely three-dimensional (3D) in the bulk crystal, and in two dimensions on the Ag(111) surface as well ...

Coexistence of one- and two-dimensional supramolecular assemblies of terephthalic acid on Pd(111) due to self-limiting deprotonation

Klaus Kern, Harald Brune, Sylvain Clair, Marta Canas Ventura

The adsorption of terephthalic acid [C6H4(COOH)(2), TPA] on a Pd(111) surface has been investigated by means of scanning tunneling microscopy (STM), x-ray photoelectron spectroscopy, and near-edge x-ray absorption fine structure spectroscopy under ultrahig ...

STM study of terephthalic acid self-assembly on Au(III): Hydrogen-bonded sheets on an inhomogeneous substrate

Klaus Kern, Harald Brune, Sylvain Clair

The adsorption and ordering of the molecule terephthalic acid (TPA), 1,4-benzene-dicarboxylic acid C6H4-(COOH)(2), on the reconstructed Au(111) surface has been studied in situ in ultrahigh vacuum by scanning tunneling microscopy (STM) at room temperature. ...
