Asymmetric quintuplet condensation in the frustrated S=1 spin dimer compound Ba3Mn2O8
E. C. Samulon, Y. Kohama, R. D. McDonald +5
Ba3Mn2O8 is a spin-dimer compound based on pairs of S = 1, 3d2, Mn5+ ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state in…
Geometric Frustration and Dimensional Reduction at a Quantum Critical Point
C. D. Batista, J. Schmalian, N. Kawashima +5
We show that the spatial dimensionality of the quantum critical point associated with Bose--Einstein condensation at T=0 is reduced when the underlying lattice comprises a set of l…
Phonon Thermal Transport of URu2Si2: Broken Translational Symmetry and Strong-Coupling of the Hidden Order to the Lattice
P. A. Sharma, N. Harrison, M. Jaime +5
A dramatic increase in the total thermal conductivity (k) is observed in the Hidden Order (HO) state of single crystal URu2Si2. Through measurements of the thermal Hall conductivit…
Irreversible dynamics of the phase boundary in U(Ru0.9)Rh0.04)2Si2 and implications for ordering
A. V. Silhanek, M. Jaime, N. Harrison +10
We report measurements and analysis of the specific heat and magnetocaloric effect at the phase boundary into the single magnetic field-induced phase (phase II) of U(Ru{0.96}Rh{0.0…
Quantum critical 5f-electrons avoid singularities in U(Ru,Rh)2Si2
A. V. Silhanek, N. Harrison, C. D. Batista +4
We present specific heat measurements of 4% Rh-doped U(Ru,Rh)2Si2 at magnetic fields above the proposed metamagnetic transition field Hm~34 T, revealing striking similarities to th…
Resistivity and magnetization of U(RuRh)Si, 2, 2.5, 3 and 4 % in magnetic fields of up to 45 T
K. H. Kim, N. Harrison, H. Amitsuka +3
This posting contains raw data used for extracting features of the phase diagram and quantum criticality versus magnetic field , temperature and Rh-doping that will soon…
