Volume Collapse Without a Structural Transition in Shock-Compressed FeO
C. Crépisson, T. Stevens, M. Fitzgerald +121
We report x-ray diffraction and emission spectroscopy of FeO under laser-driven shock compression between 31-199 GPa. FeO retains the B1 (rocksalt) structure along the Hugoniot to…
Evidence for pressure induced polarization rotation, octahedral tilting and reentrant ferroelectric phase in tetragonal (Pb0.5Bi0.5)(Ti0.5Fe0.5)O3
Pragya Singh, Chandan Upadhyay, Zuzana KonÔpková +2
Despite the technological significance of the tetragonal PbTiO3 for the piezoelectric transducer industry, its high pressure behaviour is quite controversial as two entirely differ…
Hydrogen sulfide at high pressure: change in stoichiometry
Alexander F. Goncharov, Sergey Lobanov, Ivan Kruglov +5
Hydrogen-sulfide (H2S) was studied by x-ray synchrotron diffraction (XRD) and Raman spectroscopy up to 150 GPa at 180-295 K and by quantum-mechanical variable-composition evolution…
Peierls distortion, magnetism, and high hardness of manganese tetraboride
Huiyang Gou, Alexander A. Tsirlin, Elena Bykova +10
We report crystal structure, electronic structure, and magnetism of manganese tetraboride, MnB4, synthesized under high-pressure high-temperature conditions. In contrast to superco…
