Field-induced compensation of magnetic exchange as the possible origin of reentrant superconductivity in UTe

Toni Helm, Motoi Kimata, Kenta Sudo +12

The potential spin-triplet heavy-fermion superconductor UTe exhibits signatures of multiple distinct superconducting phases. For field aligned along the axis, a metamagneti…

Three-dimensional quasi-quantized Hall insulator phase in SrSi2

Kaustuv Manna, Nitesh Kumar, Sumanta Chattopadhyay +15

In insulators, the longitudinal resistivity becomes infinitely large at zero temperature. For classic insulators, the Hall conductivity becomes zero at the same time. However, ther…

Origin of the 30 T transition in CeRhIn in tilted magnetic fields

S. Mishra, D. Gorbunov, D. J. Campbell +9

We present a comprehensive ultrasound study of the prototypical heavy-fermion material CeRhIn, examining the origin of the enigmatic 30 T transition. For a field applied at 2$^…

Robust Fermi-Surface Morphology of CeRhIn across the Putative Field-Induced Quantum Critical Point

S. Mishra, J. Hornung, M. Raba +7

We report a comprehensive de Haas--van Alphen (dHvA) study of the heavy-fermion material CeRhIn in magnetic fields up to 70~T. Several dHvA frequencies gradually emerge at high…

Observation of giant spin-split Fermi-arc with maximal Chern number in the chiral topological semimetal PtGa

Mengyu Yao, Kaustuv Manna, Qun Yang +14

Non-symmorphic chiral topological crystals host exotic multifold fermions, and their associated Fermi arcs helically wrap around and expand throughout the Brillouin zone between th…

Tuning interactions in the spin-ice materials DyGeSiO by silicon substitution

T. Stöter, M. Antlauf, L. Opherden +10

We report that the lattice constant of DyGeSiO () can be systematically reduced by substituting the non-magnetic germanium ion in the cu…

Evidence for a dynamical ground state in a frustrated pyrohafnate Tb2Hf2O7

V. K. Anand, L. Opherden, J. Xu +9

We report the physical properties of Tb2Hf2O7 based on ac magnetic susceptibility χ_ac(T), dc magnetic susceptibility χ(T), isothermal magnetization M(H), and heat capacity C_p(T)…

Evolution of antiferromagnetic domains in the all-in-all-out ordered pyrochlore NdZrO

L. Opherden, J. Hornung, T. Herrmannsdörfer +4

We report the observation of magnetic domains in the exotic, antiferromagnetically ordered all-in-all-out state of NdZrO, induced by spin canting. The all-in-all-out st…
