Title: High pressure transport and structural studies on Nb₃Ga superconductor

Abstract

We investigated the crystal structure of A-15 superconductor Nb₃Ga with a critical temperature T_c = 16.5 K by high pressure x-ray diffraction (HPXRD) using synchrotron x-rays and a diamond anvil cell under Ne pressure medium. Furthermore, the high pressure structural results indicate that Nb₃Ga is stable up to 41 GPa. The P-V plot shows an anomaly around 15 GPa even though there are no pressure induced structural transitions are observed. High pressure resistance measurements were performed up to 0.5 GPa to understand the variation of T_c under pressure. Finally, our results show a positive pressure effect on T_c.

Pressure induced structural transitions in CuSbS₂ and CuSbSe₂ thermoelectric compounds

Journal Article Baker, Jason ; Kumar, Ravhi S. ; Sneed, Daniel ; ... - Journal of Alloys and Compounds

We have investigated the structural behavior of CuSbS₂ and CuSbSe₂ thermoelectric materials under high pressure conditions up to 80 GPa using angle dispersive x-ray diffraction in a diamond anvil cell (DAC). We have also performed high-pressure Raman spectroscopy measurements up to 15 GPa. We observed a pressure-induced structural transformation from the ambient orthorhombic structure with space group Pnma to a triclinic type structure with space group P1 beginning around 8 GPa in both samples and completing at 13 GPa and 10 GPa in CuSbS₂ and CuSbSe₂, respectively. High pressure Raman experiments complement the transitions observed by high-pressure x-ray diffraction (HPXRD).more »« less

Covalency is Frustrating: La₂Sn₂O₇ and the Nature of Bonding in Pyrochlores under High Pressure–Temperature Conditions

Journal Article Childs, Christian ; Lawler, Keith V. ; Hector, Andrew L. ; ... - Inorganic Chemistry

Natural specimens of the pyrochlore (A₂B₂O₇) compounds have been found to retain foreign actinide impurities within their parent framework, undergoing metamictization to a fully amorphous state. The response to radionuclide decay identifies pyrochlore systems with having high radiation tolerance and tailored use in radioactive waste applications and radionuclide sequestration. High pressure is a powerful pathway to high density states and amorphization with parallels to radiation-induced processes. Here, La₂Sn₂O₇ is evaluated under extreme conditions via the combination of laser heating in a diamond anvil cell with X-ray diffraction and Raman spectroscopy. The measurements are supported by ab initio random structure searchingmore »« less

High-pressure effects on isotropic superconductivity in the iron-free layered pnictide superconductor ${BaPd}_{2} {As}_{2}$

Journal Article Abdel-Hafiez, M. ; Zhao, Y. ; Huang, Z. ; ... - Physical Review B

While the layered 122 iron arsenide superconductors are highly anisotropic, unconventional, and exhibit several forms of electronic orders that coexist or compete with superconductivity in different regions of their phase diagrams, we find in the absence of iron in the structure that the superconducting characteristics of the end member BaPd₂As₂ are surprisingly conventional. Here we report on complementary measurements of specific heat, magnetic susceptibility, resistivity measurements, Andreev spectroscopy, and synchrotron high pressure x-ray diffraction measurements supplemented with theoretical calculations for BaPd₂As₂. Its superconducting properties are completely isotropic as demonstrated by the critical fields, which do not depend on the directionmore »« less

A CO₂ laser heating system for in situ high pressure-temperature experiments at HPCAT

Journal Article Smith, Dean ; Smith, Jesse S. ; Childs, Christian ; ... - Review of Scientific Instruments

We present a CO₂ laser heating setup for synchrotron x-ray diffraction inside a diamond anvil cell, situated at HPCAT (Sector 16, Advanced Photon Source, Argonne National Lab, Illinois, USA), which is modular and portable between the HPCAT experiment hutches. Specifically, the system allows direct laser heating of wide bandgap insulating materials to thousands of degrees at static high pressures up to the Mbar regime. Alignment of the focused CO₂ laser spot is performed using a mid-infrared microscope, which addressed past difficulties with aligning the invisible radiation. The implementation of the mid-infrared microscope alongside a mirror pinhole spatial filter system allowsmore »« less

Effect of Pressure on Valence and Structural Properties of YbFe ₂ Ge ₂ Heavy Fermion Compound—A Combined Inelastic X-ray Spectroscopy, X-ray Diffraction, and Theoretical Investigation

Journal Article Kumar, Ravhi S. ; Svane, Axel ; Vaitheeswaran, Ganapathy ; ... - Inorganic Chemistry

We measured the crystal structure and the Yb valence of the YbFe₂Ge₂ heavy fermion compound at room temperature and under high pressures using high-pressure powder X-ray diffraction and X-ray absorption spectroscopy via both partial fluorescence yield and resonant inelastic X-ray emission techniques. Moreover, the measurements are complemented by first-principles density functional theoretical calculations using the self-interaction corrected local spin density approximation investigating in particular the magnetic structure and the Yb valence. Finally, while the ThCr₂Si₂-type tetragonal (I4/mmm) structure is stable up to 53 GPa, the X-ray emission results show an increase of the Yb valence from v = 2.72(2) atmore »« less
