Rajveer Jha, Brajesh Tiwari, and V.P.S. Awana
TL;DR
This study investigates how hydrostatic pressure affects the electrical resistivity of SrFBiS2, a parent compound of BiS2-based superconductors, revealing resistivity reduction but no superconductivity up to 2.5 GPa.
Contribution
It provides the first detailed resistivity measurements of SrFBiS2 under high pressure, enhancing understanding of its normal state properties without inducing superconductivity.
Findings
Resistivity decreases with pressure
No superconductivity observed up to 2.5 GPa
Normal state properties are pressure-sensitive
Abstract
In the present work, we measure the temperature dependent electrical resistivity from 300K down to 2K under applied hydrostatic pressure of upto 2.5GPa for SrFBiS2, which is the parent compound for the BiS2 based superconductors. Though the normal state resistivity of the compound decreases with pressure, the same is not superconducting down to 2K under applied pressure of up to 2.5Gpa.
