Electronic Spin transition in FeO: evidence for Fe(II) with peroxide O
Bo Gyu Jang, Jin Liu, Qingyang Hu +5
The discovery of FeO containing more oxygen than hematite (FeO) that was previously believed to be the most oxygen rich iron compounds, has important implications…
Magnetization reversal and negative volume thermal expansion in Fe doped Ca2RuO4
S. J. Yuan, T. F. Qi, J. Terzic +9
We report physical and structural properties of single-crystal Ca2Ru1-xFexO4 (0<x<0.20) as functions of temperature, magnetic field and pressure. Ca2RuO4 is a structurally-driven M…
Giant atomic displacement induced by built-in strain in metastable MnO
Shigeto Hirai, Antonio M. dos Santos, Maxwell C. Shapiro +6
We present x-ray, neutron scattering and heat capacity data that reveal a coupled first-order magnetic and structural phase transition of the metastable mixed-valence post-spinel c…
Pressure-induced symmetry breaking in tetragonal CsAuI3
Shibing Wang, Shigeto Hirai, Maxwell C. Shapiro +4
Results of in situ high pressure x-ray powder diffraction on the mixed valence compound Cs2Au(I)Au(III)I6 (CsAuI3) are reported, for pressures up to 21 GPa in a diamond anvil cell…
Short small-polaron lifetime in the mixed-valence perovskite CsAuI from high-pressure pump-probe experiments
M. Trigo, J. Chen, M. P. Jiang +5
We study the ultrafast phonon response of mixed-valence perovskite CsAuI using pump-probe spectroscopy under high-pressure in a diamond anvil cell. We observed a remark…
High pressure evolution of FeO electronic structure revealed by X-ray absorption
Shibing Wang, Wendy L. Mao, Adam P. Sorini +9
We report the first high pressure measurement of the Fe K-edge in hematite (FeO) by X-ray absorption spectroscopy in partial fluorescence yield geometry. The pressure-induc…
