Field-dependent thermal transport in the Haldane chain compound NENP
A. V. Sologubenko, T. Lorenz, J. A. Mydosh +3
We present a study of the magnetic field-dependent thermal transport in the spin S=1 chain material Ni(C2H8N2)2NO2(ClO4) (NENP). The measured thermal conductivity is found to be ve…
Mott-Hubbard versus charge-transfer behavior in LaSrMnO4 studied via optical conductivity
A. Gössling, M. W. Haverkort, M. Benomar +6
Using spectroscopic ellipsometry, we study the optical conductivity sigma(omega) of insulating LaSrMnO4 in the energy range of 0.75-5.8 eV from 15 to 330 K. The layered structure g…
Gamma5 quasiparticles and avoided quantum criticality in U(Ru,Rh)2Si2
N. Harrison, A. V. Silhanek, C. D. Batista +4
We discuss recent specific heat data in high magnetic fields on URu2Si2 and 4% Rh-doped URu2Si2 as well as previously published de Haas-van Alphen data at lower magnetic fields in…
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…
Ferromagnetism makes a doped semiconductor less shiny
F. P. Mena, J. F. DiTusa, D. van der Marel +5
Magnetic semiconductors have attracted interest because of the question of how a magnetic metal can be derived from a paramagnetic insulator. Here our approach is to carrier dope i…
Competition between hidden order and antiferromagnetism in URu_2Si_2 under uniaxial stress studied by neutron scattering
M. Yokoyama, H. Amitsuka, K. Tenya +4
We have performed elastic neutron scattering experiments under uniaxial stress sigma applied along the tetragonal [100], [110] and [001] directions for the heavy electron compound…
