Field-Induced Selective Spin Gap Closure and Quantum Criticality in BaNdZnS
Sangyun Lee, A. J. Woods, B. Billingsley +11
We report thermodynamic evidence for field-induced mode-selective quantum criticality in the layered rare-earth magnet BaNd2ZnS5 (BNZS). Below the Neel temperature TN = 2.9 K, spin…
Pseudo Point Nodal Superconducting Gap in Spin-Triplet UTe
S. Hosoi, K. Imamura, M. M. Bordelon +7
The unconventional superconductor UTe represents a rare example of spin-triplet pairing with potentially topologically protected quantum states. However, conflicting reports on…
Random singlet physics in exchange disordered 2D triangular YbCuSe
Caitlin S. T. Kengle, Sean M. Thomas, Roman Movshovich +5
Quantum spin liquid (QSL) phases exist in theory, but real candidate QSL materials are often extraordinarily sensitive to structural defects which disrupt the ground state. Here, w…
Quantum oscillation and topology change of the uncondensed Landau Fermi surface in superconducting CeCoIn5
Sangyun Lee, Duk. Y. Kim, Andrew J. Woods +5
Metals typically have multiple Fermi surface sheets, and when they enter the superconducting state, some electrons on these sheets may remain uncondensed, or their superconducting…
Vortex confinement through an unquantized magnetic flux
Geunyong Kim, Jinyoung Yun, Jinho Yang +7
Geometrically confined superconductors often experience a breakdown in the quantization of magnetic flux owing to the incomplete screening of the supercurrent against the field pen…
Normal Fermi Surface in the Nodal Superconductor CeCoIn Revealed via Thermal Conductivity
Sangyun Lee, Duk Y. Kim, Priscila F. S. Rosa +5
The thermal conductivity of heavy-fermion superconductor CeCoIn was measured with a magnetic field rotating in the tetragonal a-b plane, with the heat current in the anti-nodal…
Magnetic field-temperature phase diagram of spin-1/2 triangular lattice antiferromagnet KYbSe
Sangyun Lee, Andrew J. Woods, Minseong Lee +7
A quantum spin liquid (QSL) is a state of matter characterized by fractionalized quasiparticle excitations, quantum entanglement, and a lack of long-range magnetic order. However,…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
Fingerprinting Triangular-Lattice Antiferromagnet by Excitation Gaps
K. E. Avers, P. A. Maksimov, P. F. S. Rosa +5
CeCdAs is a rare-earth triangular-lattice antiferromagnet with large inter-layer separation. Our field-dependent heat capacity measurements at dilution fridge temperatures…
Domain engineering of the metastable domains in the 4f-uniaxial-ferromagnet CeRuGaB
D. Wulferding, H. Kim, I. Yang +14
In search of novel, improved materials for magnetic data storage and spintronic devices, compounds that allow a tailoring of magnetic domain shapes and sizes are essential. Good ca…
Intertwined Orders in Heavy-Fermion Superconductor CeCoIn
Duk Y. Kim, Shi-Zeng Lin, Franziska Weickert +5
The appearance of spin-density-wave (SDW) magnetic order in the low-temperature and high-field corner of the superconducting phase diagram of CeCoIn is unique among unconventio…
Observations of Pauli Paramagnetic Effects on the Flux Line Lattice in CeCoIn5
J. S. White, P. Das, M. R. Eskildsen +12
From small-angle neutron scattering studies of the flux line lattice (FLL) in CeCoIn5, with magnetic field applied parallel to the crystal c-axis, we obtain the field- and temperat…
NiX (X=pnictide, chalcogenide, or B) Based Superconductors
F. Ronning, E. D. Bauer, T. Park +6
We review the properties of Ni-based superconductors which contain Ni2X2 (X=As, P, Bi, Si, Ge, B) planes, a common structural element found also in the recently discovered FeAs sup…
