Momentum Dependence of the Nematic Order Parameter in Iron-Based Superconductors

H. Pfau, S. D. Chen, M. Yi +11

The momentum dependence of the nematic order parameter is an important ingredient in the microscopic description of iron-based high-temperature superconductors. While recent report…

Growth of nematic susceptibility in the field-induced normal state of an iron-based superconductor revealed by elastoresistivity measurements in a 65 T pulsed magnet

J. A. W. Straquadine, J. C. Palmstrom, P. Walmsley +6

In the iron-based superconductors, both nematic and magnetic fluctuations are expected to enhance superconductivity and may originate from a quantum critical point hidden beneath t…

Signatures of Anelastic Domain Relaxation in Ba(Fe $_{1 - x}$ Co $_{x}$ ) $_{2}$ As $_{2}$ Investigated by Mechanical Modulation of Resistivity

Alexander T. Hristov, Matthias S. Ikeda, Johanna C. Palmstrom +1

The resistive response of Ba(Fe $_{1 - x}$ Co $_{x}$ ) $_{2}$ As $_{2}$ to AC mechanical deformation is considered in the multi-domain state. This resistance change depends both upon the an…

AC Elastocaloric effect as a probe for thermodynamic signatures of continuous phase transitions

Matthias S. Ikeda, Joshua A. W. Straquadine, Alexander T. Hristov +5

Studying the response of materials to strain can elucidate subtle properties of electronic structure in strongly correlated materials. So far, mostly the relation between strain an…

Elastoresistive and Elastocaloric Anomalies at Magnetic and Electronic-Nematic Critical Points

Alexander T. Hristov, Matthias S. Ikeda, Johanna C. Palmstrom +2

Using Ba(Fe $_{0.975}$ Co $_{0.025}$ ) $_{2}$ As $_{2}$ as an exemplar material exhibiting second order electronic-nematic and antiferromagnetic transitions, we present measurements that re…
