Large thermomagnetic effects in weakly disordered Heisenberg chains
E. Shimshoni, D. Rasch, P. Jung +2
The interplay of different scattering mechanisms can lead to novel effects in transport. We show theoretically that the interplay of weak impurity and Umklapp scattering in spin-1/…
Magneto-thermal evidence of a partial gap at the Fermi surface of UPt_2Si_2
N. Johannsen, S. Suellow, A. V. Sologubenko +2
Motivated by the observation of a giant Nernst effect in URu_2Si_2, the thermoelectric response of the related system UPt_2Si_2 was investigated using thermal and electric transpor…
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…
Magnetothermal transport in the spin-1/2 chains of copper pyrazine dinitrate
A. V. Sologubenko, K. Berggold, T. Lorenz +4
We present experiments on the thermal transport in the spin-1/2 chain compound copper pyrazine dinitrate Cu(C_4 H_4 N_2)(NO_3)_2. The heat conductivity shows a surprisingly strong…
Thermal conductivity via magnetic excitations in spin-chain materials
A. V. Sologubenko, T. Lorenz, H. R. Ott +1
We discuss the recent progress and the current status of experimental investigations of spin-mediated energy transport in spin-chain and spin-ladder materials with antiferromagneti…
Spin thermal conductivity of the Haldane chain compound Y2BaNiO5
K. Kordonis, A. V. Sologubenko, T. Lorenz +2
We have measured the thermal conductivity of the spin S=1 chain compound Y2BaNiO5. Analyzing the anisotropy of the thermal transport allows to identify a definite spin-mediated the…
