Different multifunctional (PbTiO3, Sm0.6Nd0.4NiO3, NdMnO3) thin films were grown by metalorganic chemical vapor deposition (MOCVD) technique on SrTiO3 and LaAlO3 substrates. TEM and X-ray diffraction measurements reveal that almost single crystalline

Rare earth nickelates RENiO3 which attract interest due to their sharp metal-insulator phase transition, are instable in bulk form due to the necessity of an important oxygen pressure to stabilize Ni in its 3+ state of oxidation. Here, we report the

Raman scattering investigation across the magnetic and MI transition in rare earth nickelate RNiO3 (R = Sm, Nd) thin films

Autor: Girardot, C., Kreisel, J., Pignard, S., Caillault, N., Weiss, F.

We report a temperature-dependent Raman scattering investigation of thin film rare earth nickelates SmNiO3, NdNiO3 and Sm0.60Nd0.40NiO3, which present a metal-to-insulator (MI) transition at TMI and an antiferromagnetic-paramagnetic Neel transition a
