Strength of Correlations in a Silver Based Cuprate Analogue
Riccardo Piombo, Daniel Jezierski, Henrique Perin Martins +10
AgF2 has been proposed as a cuprate analogue which requires strong correlation and marked covalence. On the other hand, fluorides are usually quite ionic and 4d transition metals t…
Near total reflection X-ray photoelectron spectroscopy: Quantifying chemistry at solid/liquid and solid/solid interfaces
Henrique P. Martins, Giuseppina Conti, Isvar Cordova +9
Near total reflection regime has been widely used in X-ray science, specifically in grazing incidence small angle X-ray scattering and in hard X-ray photoelectron spectroscopy. In…
High resolution depth profiling using near-total-reflection hard X-ray photoelectron spectroscopy
Julien E. Rault, Cheng-Tai Kuo, Henrique P. Martins +2
By adjusting the incidence angle of incoming X-ray near the critical angle of X-ray total reflection, the photoelectron intensity is strongly modulated due to the variation of X-ra…
Layer-Resolved Many-Electron Interactions in Delafossite PdCoO2 from Standing-Wave Photoemission Spectroscopy
Qiyang Lu, Henrique Martins, J. Matthias Kahk +7
When a three-dimensional material is constructed by stacking different two-dimensional layers into an ordered structure, new and unique physical properties can emerge. An example i…
Simultaneous ambient pressure X-ray photoelectron spectroscopy and grazing incidence X-ray scattering in gas environments
H. Kersell, P. Chen, H. Martins +9
We have developed an experimental system to simultaneously observe surface structure, morphology, composition, chemical state, and chemical activity for samples in gas phase enviro…
Bulk Electronic Structure of Lanthanum Hexaboride (LaB6) by Hard X-ray Angle-Resolved Photoelectron Spectroscopy
A. Rattanachata, L. Nicolaï, H. P. Martins +11
In the last decade rare-earth hexaborides have been investigated for their fundamental importance in condensed matter physics, and for their applications in advanced technological…
Hard x-ray standing-wave photoemission study of the interfaces in a BiFeO/LaSrMnO superlattice
H. P. Martins, S. A. Khan, G. Conti +12
Hybrid multiferroics such as BiFeO (BFO) and LaSrMnO (LSMO) heterostructures are highly interesting functional systems due to their complex electronic and m…
Compensation temperatures and exchange bias in La1.5Ca0.5CoIrO6
L. T. Coutrim, E. M. Bittar, F. Stavale +8
We report on the study of magnetic properties of the La1.5Ca0.5CoIrO6 double perovskite. Via ac magnetic susceptibility we have observed evidence of weak ferromagnetism and reentra…
