Non-monotonic pressure dependence of high-field nematicity and magnetism in CeRhIn
Toni Helm, Audrey D. Grockowiak, Fedor F. Balakirev +9
CeRhIn provides a textbook example of quantum criticality in a heavy fermion system: Pressure suppresses local-moment antiferromagnetic (AFM) order and induces superconductivit…
Pressure Driven Fermi surface reconstruction of chromium
R. L. Stillwell, D. E. Graf, W. A. Coniglio +6
We have observed a massive reconstruction of the Fermi surface of single crystal chromium as a function of high pressure and high magnetic fields caused by the spin-flip transition…
Two dimensional Dirac fermions and quantum magnetoresistance in CaMnBi
Kefeng Wang D. Graf, Limin Wang, Hechang Lei +2
We report two dimensional Dirac fermions and quantum magnetoresistance in single crystals of CaMnBi. The non-zero Berry's phase, small cyclotron resonant mass and first-princip…
Quantum transport of two-dimensional Dirac fermions in SrMnBi2
Kefeng Wang, D. Graf, Hechang Lei +2
We report two-dimensional quantum transport in SrMnBi single crystals. The linear energy dispersion leads to the unusual nonsaturated linear magnetoresistance since all Dirac f…
An Experimental and Semi-Empirical Method to Determine the Pauli-Limiting Field in Quasi 2D Superconductors as applied to -(BEDT-TTF)Cu(NCS): Strong Evidence of a FFLO State
C. C. Agosta, Jing Jin, W. A. Coniglio +9
We present upper critical field data for -(BEDT-TTF)Cu(NCS) with the magnetic field close to parallel and parallel to the conducting layers. We show that we can eliminat…
Anisotropy of upper critical field in one-dimensional organic system, (TMTTF)PF under extremely high pressure
Mika Kano, Hatsumi Mori, Toshikazu Nakamura +6
We have measured the temperature dependent resistivity of (TMTTF)PF to 7 GPa using a turnbuckle DAC (diamond anvil cell) and in magnetic field up to 5 T. Unlike many other…
High resolution miniature dilatometer based on AFM piezocantilever
J. -H. Park, D. Graf, T. P. Murphy +2
Thermal expansion, or dilation, is closely related to the specific heat, and provides useful information regarding material properties. The accurate measurement of dilation in conf…
Localized f electrons in CexLa1-xRhIn5: dHvA Measurements
U. Alver, R. G. Goodrich, N. Harrison +8
Measurements of the de Haas-van Alphen effect in CexLa1-xRhIn5 reveal that the Ce 4f electrons remain localized for all x, with the mass enhancement and progressive loss of one spi…
