Evidence for bond-disproportionation in LiNiO2 from x-ray absorption spectroscopy
R. J. Green, H. Wadati, T. Z. Regier +7
The electronic structure of LiNiO, a promising Li-ion battery cathode material, has remained a challenge to understand due to its highly covalent yet correlated nature. Here we…
Determination of total x-ray absorption coefficient using non-resonant x-ray emission
A. J. Achkar, T. Z. Regier, E. J. Monkman +2
An alternative measure of x-ray absorption spectroscopy (XAS) called inverse partial fluorescence yield (IPFY) has recently been developed that is both bulk sensitive and free of s…
Magnetic Frustration in a Mn Honeycomb Lattice Induced by Mn-O-O-Mn Pathways
H. Wadati, K. Kato, Y. Wakisaka +9
We investigated the electronic structure of layered Mn oxide Bi3Mn4O12(NO3) with a Mn honeycomb lattice by x-ray absorption spectroscopy. The valence of Mn was determined to be 4+…
Bulk sensitive x-ray absorption spectroscopy free of self-absorption effects
A. J. Achkar, T. Z. Regier, H. Wadati +3
We demonstrate a new method of x-ray absorption spectroscopy (XAS) that is bulk sensitive, like traditional fluorescence yield measurements, but is not affected by self-absorption…
Interface reconstruction in V-oxide heterostructures determined by x-ray absorption spectroscopy
H. Wadati, D. G. Hawthorn, J. Geck +7
We present an x-ray absorption study of the dependence of the V oxidation state on the thickness of LaVO (LVO) and capping LaAlO (LAO) layers in the multilayer structure of…
