Antiferromagnetic Mott insulating state in single crystals of the honeycomb lattice materialNa2IrO3 [PDF]

, 2010
We have synthesized single crystals of Na2IrO3 and studied their structure, transport, magnetic, and thermal properties using powder x-ray diffraction, electrical resistivity, isothermal magnetization M versus magnetic field H, magnetic susceptibility ...

High-resolution alternating-field technique to determine the magnetocaloric effect of metals down to very low temperatures [PDF]

, 2011
The magnetocaloric effect or "magnetic Gruneisen ratio" Gamma(H) = T(-1)(dT Id H)s quantifies the cooling or heating of a material when an applied magnetic field is changed under adiabatic conditions.

Field-dependent specific heat of Yb4As3 : Agreement between a spin-1/2 model and experiment [PDF]

, 2009
We report the low-temperature specific-heat measurements on polydomain Yb4As3 at magnetic fields up to 20 T. Taking into account the Bethe ansatz results, the zero-field data have been used for the estimation of the lattice specific heat, resulting in a ...

Quantum criticality in heavy-fermion metals [PDF]

, 2008
Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy-fermion metals have in recent years emerged as prototypical systems to study quantum critical points.

Electron spin resonance of the Yb 4f-moment in Yb(Rh_1−xFe_x)₂Si₂ [PDF]

, 2013
The electron spin resonance (ESR) signal of the heavy-fermion metal YbRh2Si2 is investigated in terms of its dependence on the partial substitution of Rh by Fe.

Quantum bicriticality in the heavy-fermion metamagnet YbAgGe [PDF]

, 2013
Bicritical points, at which two distinct symmetry-broken phases become simultaneously unstable, are typical for spin-flop metamagnetism. Interestingly, the heavy-fermion compound YbAgGe also possesses such a bicritical point (BCP) with a low temperature ...

Separation of Energy Scales in Undoped YbRh2Si2 Under Hydrostatic Pressure [PDF]

, 2009
The temperature-magnetic field (T-H) phase diagram of YbRh2Si2 in the vicinity of its quantum critical point is investigated by low-T magnetization measurements.

Nonlinear conductivity in CaRuO3 thin films measured by short current pulses [PDF]

, 2014
Metals near quantum critical points have been predicted to display universal out-of-equilibrium behaviour in the steady current-carrying state. We have studied the nonlinear conductivity of high-quality CaRuO3 thin films with residual resistivity ratios ...
