Observation of the Yamaji effect in a cuprate superconductor
Mun K. Chan, Katherine A. Schreiber, Oscar E. Ayala-Valenzuela +3
The pseudogap state of high- cuprates, known for its partial gapping of the Fermi surface above the superconducting transition temperature , is believed to ho…
Anisotropic hybridization in CeRhSn
Thomas U. Böhm, Nicholas S. Sirica, Bo Gyu Jang +6
The optical conductivity of CeRhSn was studied by broadband infrared spectroscopy. Temperature-dependent spectral weight transfer occurs over high energy (eV) and t…
Excess heat capacity in magnetically ordered Ce heavy fermion metals
A. Scheie, Yu Liu, E. A. Ghioldi +5
We study the magnetic heat capacity of a series of magnetically ordered Ce-based heavy fermion materials, which show an anomalous heat capacity in excess of the phonon contri…
"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…
Chemical pressure tuning of URuSi via isoelectronic substitution of Ru with Fe
Pinaki Das, N. Kanchanavatee, J. S. Helton +8
We have used specific heat and neutron diffraction measurements on single crystals of URuFeSi for Fe concentrations 0.7 to establish that chemical substi…
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…
Observation of the hybridization gap and Fano resonance in the Kondo lattice URu2Si2
W. K. Park, P. H. Tobash, F. Ronning +4
The nature of the second order phase transition that occurs in URu2Si2 at 17.5 K remains puzzling despite intensive research over the past two and half decades. A key question emer…
Electronic Structure and Correlation Effects in PuCoIn5 as compared to PuCoGa5
Jian-Xin Zhu, P. H. Tobash, E. D. Bauer +6
Since their discovery nearly a decade ago, plutonium-based superconductors have attracted considerable interest, which is now heightened by the latest discovery of superconductivit…
Heavy Fermion scaling: Uranium versus Cerium and Ytterbium compounds
J. M. Lawrence, C. H. Wang, A. D. Christianson +1
In an effort to explore the differences between rare-earth-based and uranium-based heavy Fermion (HF) compounds that reflect the underlying difference between local 4 moments an…
Crystal-field and Kondo scale investigation of CeMIn5 (M=Co, Ir and Rh): a combined x-ray absorption and inelastic neutron study
T. Willers, Z. Hu, N. Hollmann +15
Linear polarized soft-x ray absorption (XAS) and inelastic neutron scattering (INS) experiments have been performed on CeMIn5 with M = Rh, Ir, and Co to determine the crystal-field…
