Thermodynamic and electrical transport properties of UTe under uniaxial stress
Clément Girod, Callum R. Stevens, Andrew Huxley +8
Despite intense experimental efforts, the nature of the unconventional superconducting order parameter of UTe remains elusive. This puzzle stems from different reported numbers…
Robust narrow-gap semiconducting behavior in square-net LaCdAs
Mario M. Piva, Marein C. Rahn, Sean M. Thomas +6
ABSTRACT: Narrow-gap semiconductors are sought-after materials due to their potential for long-wavelength detectors, thermoelectrics, and more recently non-trivial topology. Here w…
Skyrmion lattice creep at ultra-low current densities
Yongkang Luo, Shizeng Lin, M. Leroux +8
Magnetic skyrmions are well-suited for encoding information because they are nano-sized, topologically stable, and only require ultra-low critical current densities to depin…
Localized-to-itinerant transition preceding antiferromagnetic quantum critical point and gapless superconductivity in CeRhIrIn
Shinji Kawasaki, Toshihide Oka, Akira Sorime +9
A fundamental problem posed from the study of correlated electron compounds, of which heavy-fermion systems are prototypes, is the need to understand the physics of states near a q…
Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) have become indispensable tools in the study of correlated quantum materials. Both probe c…
Tunable quantum critical point and detached superconductivity in Al-doped CrAs
Sungmin Park, Soohyeon Shin, Sung-Il Kim +2
The origin of unconventional superconductivity and its relationship to a T=0 K continuous quantum phase transition (a quantum critical point, QCP), which is hidden inside the dome…
Imaging the magnetic states in an actinide ferromagnet UMnGe
Xinzhou Tan, Morgann Berg, Jeehoon Kim +5
We present studies of the magnetic domain structure of UMnGe single crystals using a home-built low temperature magnetic force microscope. The material has two distinct mag…
Realization of the Axial Next-Nearest-Neighbor Ising model in UAlGe
