Miniature Dilatometer Based upon an AFM Piezocantilever
Liran Wang, George M. Schmiedeshoff, David Earl Graf +4
We report on the development of a sensitive dilatometer based upon a AFM piezocantilever. This dilatometer has been tested at temperatures down to 25 mK and in magnetic fields up t…
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…
Fermi Surface of Alpha-Uranium at Ambient Pressure
D. Graf, R. Stillwell, T. P. Murphy +10
We have performed de Haas-van Alphen measurements of the Fermi surface of alpha-uranium single crystals at ambient pressure within the alpha-3 charge density wave (CDW) state from…
Pressure Evolution of a Field Induced Fermi Surface Reconstruction and of the Neel Critical Field in CeIn3
K. M. Purcell, D. Graf, M. Kano +12
We report high-pressure skin depth measurements on the heavy fermion material CeIn3 in magnetic fields up to 64 T using a self-resonant tank circuit based on a tunnel diode oscilla…
Heavy holes: precursor to superconductivity in antiferromagnetic CeIn3
Suchitra E. Sebastian, N. Harrison, C. D. Batista +7
Numerous phenomenological parallels have been drawn between f- and d- electron systems in an attempt to understand their display of unconventional superconductivity. The microscopi…
Fractalization drives crystalline states in a frustrated spin system
Suchitra E. Sebastian, N. Harrison, P. Sengupta +7
We measure a sequence of quantum Hall-like plateaux at 1/q: 9 >= q >= 2 and p/q = 2/9 fractions in the magnetisation with increasing magnetic field in the geometrically frustrated…
