Studies in superconductivity at extreme pressures

High pressure studies have played an important role in the field of superconductivity since the first experiments by Sizoo and Onnes in Leiden in 1925. A rapid dependence of the transition temperature on pressure signals that the material is capable of higher values of Tc at ambient pressure. Significant extensions of the pressure range, most recently to pressures above 1 Mbar using the diamond...

Program Behavior at Extreme Scale

Synthesis and microdiffraction at extreme pressures and temperatures.

High pressure compounds and polymorphs are investigated for a broad range of purposes such as determine structures and processes of deep planetary interiors, design materials with novel properties, understand the mechanical behavior of materials exposed to very high stresses as in explosions or impacts. Synthesis and structural analysis of materials at extreme conditions of pressure and tempera...

Magnetic ordering at anomalously high temperatures in Dy at extreme pressures

In an attempt to destabilize the magnetic state of the heavy lanthanide Dy, extreme pressures were applied in an electrical resistivity measurement to 157 GPa over the temperature range 1.3–295 K. The magnetic ordering temperature To and spin-disorder resistance Rsd of Dy, as well as the superconducting pair-breaking effect Tc in Y(1 at.% Dy), are found to track each other in a highly nonmonoto...
