High field magnetotransport and specific heat in YbAgCu4

Magnetotransport in high mobility epitaxial graphene

Epitaxial graphene layers grown on single-crystal SiC have large structural coherence domains and can be easily patterned into submicron structures using standard microelectronics lithography techniques. Patterned structures show two-dimensional electron gas properties with mobilities exceeding 3 m2/Vs. Magnetotransport measurements (Shubnikov–de Haas oscillations) indicate that the transport p...

Field-dependent specific heat and multiple superconducting phases in UPt3.

High magnetic field study of the specific heat of CeB6 and LaB6

2014 The specific heats of CeB6 and LaB6 have been measured over a large range of temperatures and under magnetic fields up to 8 teslas. The data confirm that the intermediate phase of CeB6, the so-called phase II, is favoured by an applied magnetic field Actually both the transition temperature and the associated specific heat anomaly are strongly increased by a magnetic field. To get the magn...

Comparative high-field magnetotransport of the oxypnictide superconductors RFeAsO1−xFx (R=La, Nd) and SmFeAsO1−

We compare magnetotransport of the three iron-arsenide-based compounds ReFeAsO Re=La, Sm, Nd in very high DC and pulsed magnetic fields up to 45 and 54 T, respectively. Each sample studied exhibits a superconducting transition temperature near the maximum reported to date for that particular compound. While high magnetic fields do not suppress the superconducting state appreciably, the resistiv...
