2-D assembly of supramolecular nanoarchitectures on Mg(0001)

Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto, Bart Willem Stel, Daniel Eduardo Hurtado Salinas

In this work, a Mg(0001) single crystal is used as a novel template to grow 2D supramolecular nano-architectures. By using scanning tunnelling microscopy (STM) and high-resolution X-ray photoemission spectroscopy (HR-XPS), the formation of either a homo-mo ...

Mapping the lattice dynamical anomaly of the order parameters across the Verwey transition in magnetite

Henrik Moodysson Rønnow, Fabrizio Carbone, Andrea Pisoni, Gregory Scott Tucker, Francesco Pennacchio, Simone Borroni

We present inelastic neutron scattering data across the Verwey transition in magnetite, obtained for a single crystal via a detwinning method. We provide direct evidence of the influence of the charge order on the transverse-acoustic phonons, associated wi ...

Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates

Claudia Giuseppina Fatuzzo

In materials where electrons interact strongly, a number of exotic and exciting phenomena arise. The mechanisms at the base of many of these phenomena remain debated, as strongly correlated electron physics represents one of the biggest challenges for mode ...

Indium selenide: an insight into electronic band structure and surface excitations

Davide Campi

We have investigated the electronic response of single crystals of indium selenide by means of angle-resolved photoemission spectroscopy, electron energy loss spectroscopy and density functional theory. The loss spectrum of indium selenide shows the direct ...

Thermal induced structural properties of silver(I) sulphate (Ag2SO4)

Philip Pattison

The crystal structures of silver(I) sulphate, Ag2SO4, have been investigated as a function of temperature. A main feature is the phase transition from the low-temperature ordered phase, F ddd, to the high-temperature disordered phase, P63/mmc. In particula ...

The low-temperature crystal structure of the multiferroic melilite Ca2CoSi2O7

Bálint Náfrádi

In the antiferromagnetic ground state, below T-N similar or equal to 5.7 K, Ca2CoSi2O7 exhibits strong magnetoelectric coupling. For a symmetry-consistent theoretical description of this multiferroic phase, precise knowledge of its crystal structure is a p ...

Consequences of Broken Translational Symmetry in FeSexTe1-x

Marco Grioni, Luca Moreschini, Ping-Hui Lin, Davide Innocenti

We investigate the consequences of broken translational symmetry in the superconductor FeSexTe1-x using angle-resolved photoemission spectroscopy. We find that the intensity does not follow the periodicity dictated by the crystal structure, owing to the fo ...
