Nuclear magnetic resonance investigation of the heavy fermion system CeCoAlGe
A. P. Dioguardi, P. Guzman, P. F. S. Rosa +6
We present nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements performed on single crystalline \ccag{}, a member of a recently discovered family of…
Resonant torsion magnetometry in anisotropic quantum materials
K. A. Modic, Maja D. Bachmann, B. J. Ramshaw +12
Unusual behavior of quantum materials commonly arises from their effective low-dimensional physics, which reflects the underlying anisotropy in the spin and charge degrees of freed…
Tunable Emergent Heterostructures in a Prototypical Correlated Metal
David M Fobes, S. Zhang, S. -Z. Lin +13
At the interface between two distinct materials desirable properties, such as superconductivity, can be greatly enhanced, or entirely new functionalities may emerge. Similar to in…
Realization of the Axial Next-Nearest-Neighbor Ising model in UAlGe
David M Fobes, Shi-Zeng Lin, Nirmal J Ghimire +5
Here we report small-angle neutron scattering (SANS) measurements and theoretical modeling of UAlGe. Analysis of the SANS data reveals a phase transition to sinusoidall…
Quantum limit transport and destruction of the Weyl nodes in TaAs
B. J. Ramshaw, K. A. Modic, Arkady Shekhter +12
Weyl fermions are a new ingredient for correlated states of electronic matter. A key difficulty has been that real materials also contain non-Weyl quasiparticles, and disentangling…
Investigation of the physical properties of the Ce2MAl7Ge4 (M = Co, Ir, Ni, Pd) heavy fermion compounds
Nirmal J. Ghimire, S. K. Cary, S. Eley +10
We report the synthesis, crystal structure and characterization by means of single crystal x-ray diffraction, neutron powder diffraction, magnetic, thermal and transport measuremen…
Anomalous electronic structure and magnetoresistance in TaAs
Yongkang Luo, R. D. McDonald, P. F. S. Rosa +6
The resistance of a metal in a magnetic field can be very illuminating about its ground state. Some famous examples include the integer and fractional quantum Hall effects\cite{Kli…
"Hard" crystalline lattice in the Weyl semimetal NbAs
Yongkang Luo, N. J. Ghimire, E. D. Bauer +2
We report the effect of hydrostatic pressure on the magnetotransport properties of the Weyl semimetal NbAs. Subtle changes can be seen in the profiles with pressure up…
Electron-hole compensation effect between topologically trivial electrons and nontrivial holes in NbAs
Yongkang Luo, N. J. Ghimire, M. Wartenbe +7
Via angular Shubnikov-de Hass (SdH) quantum oscillations measurements, we determine the Fermi surface topology of NbAs, a Weyl semimetal candidate. The SdH oscillations consist of…
Investigation of the physical properties of the tetragonal CeMAl4Si2 (M = Rh, Ir, Pt) compounds
N. J. Ghimire, F. Ronning, D. J. Williams +4
The synthesis, crystal structure, and physical properties studied by means of x-ray diffraction, magnetic, thermal and transport measurements of CeMAlSi (M = Rh, Ir, Pt…
The magnitude of the magnetic exchange interaction in the heavy fermion antiferromagnet CeRhIn
Pinaki Das, S. -Z. Lin, N. J. Ghimire +7
We have used high-resolution neutron spectroscopy experiments to determine the complete spin wave spectrum of the heavy fermion antiferromagnet CeRhIn. The spin wave dispersion…
