Correlation between Electronic Configuration and Magnetic Stability in Dysprosium Single Atom Magnets

Harald Brune, Stefano Rusponi, Marina Pivetta, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Christian Wäckerlin, Aparajita Singha, Romana Baltic, Edgar Fernandes, Jean-Guillaume De Groot

Single atom magnets offer the possibility of magnetic information storage in the most fundamental unit of matter. Identifying the parameters that control the stability of their magnetic states is crucial to design novel quantum magnets with tailored proper ...

Competing Interactions in the Self-Assembly of NC-Ph-3-CN Molecules on Cu(111)

Harald Brune, Marina Pivetta, Giulia Elisabetta Pacchioni

We report on low-temperature scanning tunneling microscopy and spectroscopy measurements on NC-Ph-3-CN molecules adsorbed at 300 K on a Cu(111) surface. Upon cooling, the molecules form chain and honeycomb structures, incorporating Cu adatoms supplied by t ...

The Impact of Lattice Distortions on the Magnetic Stability of Single Atoms: Dy and Ho on BaO(100)

Harald Brune, Stefano Rusponi, Marina Pivetta, Darius Constantin Merk, Boris Sorokin, Sébastien Reynaud

X-ray magnetic circular dichroism, atomic multiplet simulations, and density functional theory calculations are employed to identify criteria for the optimum combination of supporting alkaline earth oxide and adsorption site maximizing the spin lifetimes o ...

Gap opening in the surface electronic structure of graphite induced by adsorption of alkali atoms: Photoemission experiments and density functional calculations

Wolf-Dieter Schneider, François Patthey, Marina Pivetta

2005

Direct capture and electrostatic repulsion in the self-assembly of rare-earth atom superlattices on graphene

Harald Brune, Stefano Rusponi, Marina Pivetta

2018

Formation of Fe Cluster Superlattice in a Metal-Organic Quantum-Box Network

Harald Brune, Marina Pivetta, Uta Schlickum, Giulia Elisabetta Pacchioni

We report on the self-assembly of Fe adatoms on a Cu(111) surface that is patterned by a metal-organic honeycomb network, formed by coordination of dicarbonitrile pentaphenyl molecules with Cu adatoms. Fe atoms landing on the metal surface are mobile and s ...

Fluorescence and phosphorescence from individual C-60 molecules excited by local electron tunneling

Majed Chergui, Wolf-Dieter Schneider, François Patthey, Marina Pivetta, Elizabeta Cavar

Using the highly localized current of electrons tunneling through a double barrier scanning tunneling microscope junction, we excite luminescence from a selected C60 mol. in the surface layer of fullerene nanocrystals grown on an ultrathin NaCl film on Au( ...
