Changes induced by transition metal oxides in Pt nanoparticles unveil the effects of electronic properties on oxygen reduction activity
(2019-01-01)
Although the relevance of electronic effects in the electrocatalysis of the oxygen reduction reaction has been recognized, the impossibility of separating the effects of composition and particle size for Pt-based materials ...
Effect of transition metal doping on the crystal structure and oxidation state of Sr2MgMo0.9TM0.1O6− compounds (TM = Co, Mn or Ni)
(Pergamon-Elsevier Science Ltd, 2019-12)
We analyse the effects of the partial replacement of Mo by transition metals (Co, Mn or Ni) on the electronic and structural properties of Sr2MgMo0.9TM0.1O6−δ (SMMTM; TM is Co, Mn or Ni) compounds. The crystal structure ...
Magnetic interactions and spin-reversal mechanism in ErMn1-xCoxO3-delta samples
(Springer, 2011-12-01)
Manganese-based oxides present a very complex magnetic phase diagram, and many of their basic physical properties and magnetic interaction need more exploration. At the crystallographic level, the magnetic properties of ...

Tuning the insulator-metal transition in oxide interfaces: an ab initio study exploring the role of oxygen vacancies and cation interdiffusion
(Wiley VCH Verlag, 2014-07)
We investigate the structural, electronic, and magnetic properties of a particular interface in the oxide heterostructures LaAlOmath formula/SrTiOmath formula (LAO/STO) and TiOmath formula-anatase/LaAlOmath formula (TiOmath ...
Structural transition of ZnO thin films produced by RF magnetron sputtering at low temperatures
(2013-09-01)
Zinc oxide (ZnO) thin films were prepared using reactive radio-frequency magnetron sputtering of a pure metallic zinc target onto glass substrates. The evolution of the surface morphology and the optical properties of the ...
