Abstract The wide tunability of strongly correlated transition metal (TM) oxides stems from their complex electronic properties and the coupled degrees of freedom. Among the perovskite oxides family, LaMO3 (M = Ti-Ni) allows an M-dependent systematic

Autor: Leonardo Martinelli, Davide Betto, Kurt Kummer, Riccardo Arpaia, Lucio Braicovich, Daniele Di Castro, Nicholas B. Brookes, Marco Moretti Sala, Giacomo Ghiringhelli
Publikováno v: Physical Review X, Vol 12, Iss 2, p 021041 (2022)
We use resonant inelastic x-ray scattering (RIXS) to investigate the magnetic dynamics of the infinite-layer cuprate CaCuO_{2}. We find that close to the (1/2,0) point, the single magnon decays into a broad continuum of excitations accounting for abo

De Luca, Daniele Di Castro, Kurt Kummer, Marco Moretti Sala, Mattia Pagetti, Giuseppe Balestrino, Nicholas B. Brookes, Marco Salluzzo, Steven Johnston, Jeroen van den Brink, Giacomo Ghiringhelli
Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023231 (2020)
The coupling between lattice vibration quanta and valence electrons can induce charge-density modulations and decisively influence the transport properties of materials, e.g., leading to conventional superconductivity. In high-critical-temperature su

Pressure induced phase separation in optimally doped bilayer manganites
Autor: Lorenzo, Malavasi, Baldini, M., Ilaria, Zardo, Michael, Hanfland, DANIELE DI CASTRO, Postorino, Paolo
Publikováno v: Applied Physics Letters. 94:061907
In this paper, we give a direct experimental evidence of the long hypothesized phase separation scenario in strongly correlated manganite-based systems. High resolution, high-pressure synchrotron x-ray diffraction measurements on La1.4Sr1.6Mn2O7 as a
