Entropy mapping under uniaxial pressure utilizing the elastocaloric effect
Zhenhai Hu, You-Sheng Li, Aleksei V. Frolov +8
Uniaxial pressure is a powerful tuning parameter for quantum materials, but conventional thermodynamic probes such as specific heat are difficult to realize in the constrained geom…
Uniaxial-Stress-Induced Magnetic Transitions in the Triangular-Lattice Antiferromagnet PdCrO2
Nina Stilkerich, Tobias Ritschel, Hilary M. L. Noad +10
Uniaxial stress is a promising method to tune magnetic frustration, allowing its effects to be studied in a precise way. In this work, uniaxial stress is applied to the triangular-…
Strain continuously rotates the Néel vector in altermagnetic MnTe
Alex Liebman-Peláez, Jon Kruppe, Resham Babu Regmi +7
Altermagnetism has recently emerged as a distinct class of collinear antiferromagnets that break time-reversal symmetry, exhibiting a host of novel properties. Applied strain has a…
Probing multipolar order in the candidate altermagnet MnF through the elastocaloric effect under strain
Rahel Ohlendorf, Luca Buiarelli, Hilary M. L. Noad +5
Altermagnets break a combination of time-reversal and rotational symmetries without generating a net magnetization. As such, the order parameter of -wave altermagnets has the sa…
Determination of the dynamic Young's modulus of quantum materials in piezoactuator-driven uniaxial pressure cells using a low-frequency a.c. method
Caitlin I. O'Neil, Zhenhai Hu, Naoki Kikugawa +4
We report on a new technique for measuring the dynamic Young's modulus, , of quantum materials at low temperatures as a function of static tuning strain, , in piezoactuator-d…
Controllable suppression of the unconventional superconductivity in bulk and thin-film SrRuO via high-energy electron irradiation
Jacob P. Ruf, Hilary M. L. Noad, Romain Grasset +11
In bulk SrRuO, the strong sensitivity of the superconducting transition temperature to nonmagnetic impurities provides robust evidence for a superconduct…
