Electronic structure of pristine and Ni-substituted LaFeO3 from near edge x-ray absorption fine structure experiments and first-principles simulations

Nicola Marzari, Iurii Timrov, Artur Braun, Matteo Cococcioni, Xinyu Zhang, Daniele Passerone, Piyush Agrawal

We present a joint theoretical and experimental study of the oxygen K-edge spectra for LaFeO3 and homovalent Ni-substituted LaFeO3 (LaFe0.75Ni0.25O3), using first-principles simulations based on density-functional theory with extended Hubbard functionals a ...

Delivery of a Masked Uranium(II) by an Oxide-Bridged Diuranium(III) Complex

Marinella Mazzanti, Farzaneh Fadaei Tirani

Oxide is an attractive linker for building polymetallic complexes that provide molecular models for metal oxide activity, but studies of these systems are limited to metals in high oxidation states. Herein, we synthesized and characterized the molecular an ...

Length scales of interfacial coupling between metal and insulator phases in oxides

Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone

The characteristic length scale and mechanism of the metal-insulator transition in nickelate superlattices is addressed, with implications for the design of oxide electronics. Controlling phase transitions in transition metal oxides remains a central featu ...

Spin Excitations in a 4f-3d Heterodimer on MgO

Harald Brune, François Patthey, Christian Wäckerlin, Fabio Donati, Donat Fabian Natterer, Aparajita Singha, Zeljko Sljivancanin

We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic compound of a lanthanide and a transition metal atom. The dimers are adsorbed on ultrathin MgO(100) films grown on Ag(100). New for 4f elements, we detect ...

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 ...

Lattice, spin and orbital excitations in selected transition metal oxides

Sara Fatale

Transition metal compounds represent a unique class of solids characterized by a surprising richness of physical properties. They display many phenomena and represent the main area of interest for the research on strongly correlated materials. Many novel i ...

Electronic Phase Separation and Dramatic Inverse Band Renormalization in the Mixed-Valence Cuprate LiCu2O2

Marco Grioni, Arnaud Magrez, Helmuth Berger, Philippe Bugnon, Luca Moreschini, Simon Karl Moser, Gianmarco Gatti

We measured, by angle-resolved photoemission spectroscopy, the electronic structure of LiCu2O2, a mixed-valence cuprate where planes of Cu(I) (3d(10)) ions are sandwiched between layers containing one-dimensional edge-sharing Cu(II) (3d(9)) chains. We find ...
