Boosted magnetic fluctuations at the onset of superconductivity in UTe beyond 40 T
T. Thebault, K. Somesh, G. Lapertot +11
Several unconventional superconducting phases have been discovered close to a metamagnetic transition in the heavy-fermion compound UTe. Although suspected to be of magnetic na…
Bulk signatures of re-entrant superconductivity in UTe from ultrasound measurements
N. Marquardt, C. Duffy, C. Proust +7
We report bulk ultrasound measurements up to 80 T and down to 0.5 K of the field re-entrant superconducting phase of the unconventional superconductor UTe. Clear bulk signature…
Visualization of vortex sheets and half quantum vortices in the chiral odd-parity superconductor UPt
P. GarcÃa-Campos, V. O. Dolocan, A. D. Huxley +3
Superconductivity is characterized by vanishing electrical resistance and magnetic flux expulsion. For conventional type II superconductors, the magnetic flux expulsion is incomple…
Anisotropic collapse of electronic correlations in the ferromagnet UGe under high magnetic field
K. Somesh, T. Thebault, V. Taufour +5
We present electrical-resistivity measurements on the prototypical heavy-fermion ferromagnet UGe under pulsed magnetic field up to 60~T. An anisotropic field-induced suppressio…
Slow magnetic quantum oscillations in the c-axis magnetoresistance of UTe
Freya Husstedt, Motoi Kimata, Sajal Naduvile Thadathil +8
Details of the electronic band structure in unconventional superconductors are key to the understanding of their fundamental ground state. The potential spin-triplet superconductor…
Exotic magnetic phase diagram and extremely robust antiferromagnetism in CeRhIn
T. Klein, C. Marcenat, A. Demuer +3
The antiferromagnetic heavy-fermion compound CeRhIn belongs to the same family and bears similarities with the well-studied prototypical material CeRhIn, which demonstr…
