Structural Phase Transformations in Iron-Chalcogen under High Pressures
Andrew K. Stemshorn, Yogesh K. Vohra, Phillip M. Wu +4
We report high pressure structural phase transformation sequence in a layered Iron-based superconducting compound FeSe0.3Te0.7 to 31 GPa at room temperature. The ambient pressure P…
Formation of Collapsed Tetragonal Phase in EuCo2As2 under High Pressure
Matthew Bishop, Walter Uhoya, Georgiy Tsoi +3
The structural properties of EuCo2As2 have been studied up to 35 GPa, through the use of x-ray diffraction in a diamond anvil cell at a synchrotron source. At ambient conditions, E…
Structural and Magnetic Phase Transitions in NdCoAsO under High Pressures
Walter Uhoya, Georgiy M. Tsoi, Yogesh K. Vohra +5
We have investigated structural and magnetic phase transitions under high pressures in a quaternary rare earth transition metal arsenide oxide NdCoAsO compound that is isostructura…
Anomalous Compressibility Effects and Superconductivity in EuFe2As2 under High Pressures
Walter Uhoya, Georgiy M. Tsoi Yogesh K. Vohra, Michael A. McGuire +4
The crystal structure and electrical resistance of the structurally-layered EuFe2As2 have been studied up to 70 GPa and down to temperature of 10 K, using a synchrotron x-ray sourc…
