Anomalous Tunneling Systems in Amorphous Organic Materials
S. Sahling, M. Koláč, V. L. Katkov +1
We compare the heat release data of organic glasses with that of amorphous and glass like crystalline solids. Anomalous behavior was found in all these materials, which disagrees w…
Anomalous Isotopic Effect of Tunneling States in NbTi-H/D
S. Sahling, S. Abens, V. L. Katkov +1
The thermal conductivity, heat capacity and heat release of NbTi, NbTi-H and NbTi-D were measured at low temperatures. All three systems reveal low temperature anomalies typical fo…
Relaxation time spectrum of low-energy excitations in one- and two-dimensional materials with charge or spin density waves
S. Sahling, G. Remenyi, J. E. Lorenzo +3
The long-time thermal relaxation of (TMTTF)Br, SrCuO and SrCaCuO single crystals at temperatures below 1 K and magnetic field up t…
Spin dynamics in the presence of competing ferro- and antiferro-magnetic correlations in Yb2Ti2O7
J. Robert, E. Lhotel, G. Remenyi +5
In this work, we show that the zero field excitation spectra in the quantum spin ice candidate pyrochlore compound \ybti\ is a continuum characterized by a very broad and almost fl…
Equilibrium Low Temperature Heat Capacity of the Spin Density Wave compound (TMTTF)2 Br: effect of a Magnetic Field
S. Sahling, J. C. Lasjaunias, R. Mélin +2
We have investigated the effect of the magnetic field (B) on the very low-temperature equilibrium heat capacity ceq of the quasi-1 D organic compound (TMTTF)2Br, characterized by a…
Interplay between phase defects and spin polarization in the specific heat of the spin density wave compound (TMTTF)_2Br in a magnetic field
R. Mélin, J. C. Lasjaunias, S. Sahling +2
Equilibrium heat relaxation experiments provide evidence that the ground state of the commensurate spin density wave (SDW) compound (TMTTF)Br after the application of a suffici…
