Abstract

Using ultrafast resonant soft x-ray diffraction, we demonstrate photoinduced melting of antiferromagnetic order in the correlated electron insulator NdNiO 3 . Time-dependent analysis of the resonant diffraction spectra allows us to follow the temporal evolution of the charge imbalance between adjacent Ni sites. A direct correlation between the melting of magnetic order and charge rebalancing is found. Furthermore, we demonstrate that the magnetic ordering on the Ni and Nd sites, which are locked together in equilibrium, become decoupled during this nonthermal process., QN/Quantum Nanoscience, Applied Sciences

3. Unusual temperature dependence of the spectral weight near the Fermi level of NdNiO₃ thin films

Author

Schwier, Eike Fabian, Scherwitzl, R., Vydrovà, Z., García-Fernández, Mirian, Gibert, M., Zubko, P., Garnier, Michael G., Triscone, J.-M., Aebi, Philipp, Schwier, Eike Fabian, Scherwitzl, R., Vydrovà, Z., García-Fernández, Mirian, Gibert, M., Zubko, P., Garnier, Michael G., Triscone, J.-M., and Aebi, Philipp

Abstract

We investigate the behavior of the spectral weight near the Fermi level of NdNiO3 thin films as a function of temperature across the metal-to-insulator transition (MIT) by means of ultraviolet photoelectron spectroscopy. The spectral weight was found to exhibit thermal hysteresis, similar to that of the dc conductivity. A detailed analysis of the temperature dependence reveals two distinct regimes of spectral loss close to the Fermi level. The temperature evolution of one regime is found to be independent of the MIT.
