Probing quantum criticality in an iron-based superconductor with symmetry-breaking strain
Abstract/Contents
- Abstract
- In this thesis, I study the effect of the symmetry-preserving strain and the orthogonal antisymmetric strain to the critical temperature of the nematic phase transition (Ts) in a prototypical iron-based superconductor, BaFe2As2. The result establishes both strains as effective tuning parameters. This perspective is the utilized to systematically study the effect of these strain to Ts in the cobalt-doping series of BaFe2As2. A power-law behavior of the critical temperature was observed as a function of the combined tuning parameters, which is a linear combination the strains and the cobalt concentration. This provides the first clear evidence for power-law behavior of the critical temperature as a function of non-thermal tuning parameters. Lastly, I proposed an experiment that permits the measurement of the nematic susceptibility while continuously tuning the critical temperature with strain.
