Giant elastocaloric effect at low temperatures in TmVO and implications for cryogenic cooling
Mark P. Zic, Matthias S. Ikeda, Pierre Massat +6
Adiabatic decompression of para-quadrupolar materials has significant potential as a cryogenic cooling technology. We focus on TmVO, an archetypal material that undergoes a con…
The nematic susceptibility of the ferroquadrupolar metal TmAg2 measured via the elastocaloric effect
Elliott W. Rosenberg, Matthias Ikeda, Ian R. Fisher
Elastocaloric measurements of the ferroquadrupolar/nematic rare-earth intermetallic TmAg are presented. TmAg undergoes a cooperative Jahn-Teller-like ferroquadrupolar phase…
Elastocaloric signatures of symmetric and antisymmetric strain-tuning of quadrupolar and magnetic phases in DyB2C2
Linda Ye, Yue Sun, Veronika Sunko +7
The adiabatic elastocaloric effect measures the temperature change of given systems with strain and probes the entropic landscape in the temperature-strain space. In this study we…
Frequency-dependent sensitivity of AC elastocaloric effect measurements explored through analytical and numerical models
J. A. W. Straquadine, M. S. Ikeda, I. R. Fisher
We present a comprehensive study of the frequency-dependent sensitivity for measurements of the AC elastocaloric effect by applying both exactly soluble models and numerical method…
Evidence for realignment of the charge density wave state in ErTe and TmTe under uniaxial stress via elastocaloric and elastoresistivity measurements
J. A. W. Straquadine, M. S. Ikeda, I. R. Fisher
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides (Te for =Er,Tm) as a function of in-plane uniaxial stress. Measureme…
Nematic quantum criticality in an Fe-based superconductor revealed by strain-tuning
Thanapat Worasaran, Matthias S. Ikeda, Johanna C. Palmstrom +3
Quantum criticality has been invoked as being essential to the understanding of a wide range of exotic electronic behavior, including heavy Fermion and unconventional superconducti…
Signatures of Anelastic Domain Relaxation in Ba(FeCo)As Investigated by Mechanical Modulation of Resistivity
Alexander T. Hristov, Matthias S. Ikeda, Johanna C. Palmstrom +1
The resistive response of Ba(FeCo)As to AC mechanical deformation is considered in the multi-domain state. This resistance change depends both upon the an…
Elastoresistive and Elastocaloric Anomalies at Magnetic and Electronic-Nematic Critical Points
Alexander T. Hristov, Matthias S. Ikeda, Johanna C. Palmstrom +2
Using Ba(FeCo)As as an exemplar material exhibiting second order electronic-nematic and antiferromagnetic transitions, we present measurements that re…
