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…
Thermal expansion of the magnetically ordering intermetallics RTMg (R = Eu, Gd and T = Ag, Au)
J. Rohrkamp, O. Heyer, T. Fickenscher +5
We report measurements of the thermal expansion for two Eu- and two Gd-based intermetallics which exhibit ferro- or antiferromagnetic phase transitions. These materia…
Insulator to semiconductor transition and magnetic properties of the one-dimensional S = 1/2 system In_2VO_5
A. Moller, T. Taetz, N. Hollmann +5
We report structural, magnetization, electrical resistivity and nuclear- and electron spin resonance data of the complex transition metal oxide In_2VO_5 in which structurally well-…
Nernst Effect in NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}
N. Johannsen, Th. Wolf, A. V. Sologubenko +3
In NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}, magnetic Ni-impurities suppress Tc but at the same time the pseudogap is strongly enhanced. This unique feature makes it an ideal system to study…
Anomalous thermal expansion and strong damping of the thermal conductivity of NdMnO and TbMnO due to 4f crystal-field excitations
K. Berggold, J. Baier, D. Meier +6
We present measurements of the thermal conductivity and the thermal expansion of NdMnO and TbMnO. In both compounds a splitting of the multiplet of the $R^{3+}…
