Disappearance of spin glass behavior in ThCr2Si2-type intermetallic PrAu2Si2
D. X. Li, Y. Shimizu, A. Nakamura +5
It is unexpected that a spin-glass transition, which generally occurs only in the system with some form of disorder, was observed in the ThCr2Si2-type compound PrAu2Si2 at a temper…
Feedback of superconductivity on the magnetic excitation spectrum of UTe
S. Raymond, W. Knafo, G. Knebel +5
We investigate the spin dynamics in the superconducting phase of UTe by triple-axis inelastic neutron scattering on a single crystal sample. At the wave-vector =(0,…
Low-dimensional antiferromagnetic fluctuations in the heavy-fermion paramagnetic ladder UTe
W. Knafo, G. Knebel, P. Steffens +7
Inelastic-neutron-scattering measurements were performed on a single crystal of the heavy-fermion paramagnet UTe above its superconducting temperature. We confirm the presence…
Magnetic Properties under Pressure in Novel Spin-Triplet Superconductor UTe2
Dexin Li, Ai Nakamura, Fuminori Honda +8
We report the magnetic susceptibility and the magnetization under pressures up to 1.7GPa above the critical pressure, Pc ~ 1.5GPa, for H // a, b, c-axes in the novel spin triplet s…
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$^…
Field-Induced Superconductivity near the Superconducting Critical Pressure in UTe2
Dai Aoki, Motoi Kimata, Yoshiki J. Sato +12
We report the magnetoresistance in the novel spin-triplet superconductor UTe2 under pressure close to the critical pressure Pc, where the superconducting phase terminates, for fiel…
Pressure induced multicriticality and electronic instability in quasi-kagome ferromagnet URhSn
Arvind Maurya, Dilip Bhoi, Fuminori Honda +9
We report an unconventional class of pressure induced quantum phase transition, possessing two bicritical points at 6.25 GPa in URhSn. This unique transformation accompanies a Ferm…
Specific heat of CeRhIn in high magnetic fields: Magnetic phase diagram revisited
S. Mishra, A. Demuer, D. Aoki +1
CeRhIn is a prototypical antiferromagnetic heavy-fermion compound, whose behavior in a magnetic field is unique. A magnetic field applied in the basal plane of the tetragonal c…
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…
