Ground state oxygen holes and the metal-insulator transition in the negative charge transfer rare-earth nickelates
Valentina Bisogni, Sara Catalano, Robert J. Green +9
The metal-insulator transitions and the intriguing physical properties of rare-earth perovskite nickelates have attracted considerable attention in recent years. Nonetheless, a com…
Spatially resolved ultrafast magnetic dynamics launched at a complex-oxide hetero-interface
M. Först, A. D. Caviglia, R. Scherwitzl +18
Static strain in complex oxide heterostructures has been extensively used to engineer electronic and magnetic properties at equilibrium. In the same spirit, deformations of the cry…
Electronic Transitions in Strained SmNiO_3 Thin Films
S. Catalano, M. Gibert, V. Bisogni +10
Nickelates are known for their metal to insulator transition (MIT) and an unusual magnetic ordering, occurring at T=T_Néel. Here, we investigate thin films of SmNiO_3 subjected to…
Unusual temperature dependence of the spectral weight near the Fermi level of NdNiO3 thin films
E. F. Schwier, R. Scherwitzl, Z. Vydrova +7
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…
Ultrafast strain engineering in complex oxide heterostructures
A. D. Caviglia, R. Scherwitzl, P. Popovich +11
We report on ultrafast optical experiments in which femtosecond mid-infrared radiation is used to excite the lattice of complex oxide heterostructures. By tuning the excitation ene…
