Proton diffusivity in the BaZr0.9Y0.1O3-δ proton conductor
Artur Braun, Sophie Duval, Peter Ried +7
The thermally activated proton diffusion in BaZr0.9Y0.1O3-δ was studied with electrochemical impedance spectroscopy (IS) and quasi-elastic neutron scattering (QENS) in the temperat…
Quantitative model for anisotropy and reorientation thickness of the magnetic moment in thin epitaxially strained metal films
Artur Braun
A quantitative mathematical model for the critical thickness of strained epitaxial metal films is presented, at which the magnetic moment experiences a reorientation from in-plane…
Protons in lattice confinement: Static pressure on the Y-substituted, hydrated BaZrO3 ceramic proton conductor decreases proton mobility
Qianli Chen, Artur Braun, Alejandro Ovalle +3
Yttrium substituted BaZrO3, with nominal composition BaZr0.9Y0.1O3, a ceramic proton conductor, was subject to impedance spectroscopy for temperatures 300 K < T < 715 K at mechanic…
Evolution of an oxygen NEXAFS transition in the upper Hubbard band in α-Fe2O3 upon electrochemical oxidation
Debajeet K. Bora, Artur Braun, Selma Erat +6
Electrochemical oxidation of hematite (α-Fe2O3) nano-particulate films at 600 mV vs. Ag+/AgCl reference in KOH electrolyte forms a species at the hematite surface which causes a ne…
Fe-resonant valence band photoemission and oxygen NEXAFS study on La1-xSrxFe0.75Ni0.25O3-δ
Selma Erat, Hiroki Wadati, Funda Aksoy +4
Iron resonant valance band photoemission spectra of Sr substituted LaFe0.75Ni0.25 O3-δ have been recorded across the Fe 2p - 3d absorption threshold to obtain Fe specific spectral…
Correlation of conductivity and angle integrated valence band photoemission characteristics in single crystal iron perovskites for 300 K < T < 800 K: Comparison of surface and bulk sensitive methods
A. Braun, B. S. Mun, Y. Sun +9
A single crystal monolith of La0.9Sr0.1FeO3 and thin pulsed laser deposited film of La0.8Sr0.2Fe0.8Ni0.2O3 were subject to angle integrated valence band photoemission spectroscopy…
