Acoustic Properties of Amorphous Solids at Very Low Temperatures: The Quest for Interacting Tunneling States
Pablo Esquinazi, Miguel A. Ramos, Reinhard König
We discuss the strain dependence of the acoustic properties of amorphous metals in both normal and superconducting states, in the temperature range 0.1 mK K. A cross…

Strain dependence of the acoustic properties of amorphous metals below 1K: Evidence for the interaction between tunneling states
R. Koenig, M. A. Ramos, I. Usherov-Marshak +3
We have conducted a thorough study of the acoustic properties between 10^-4 and 1 Kelvin for the amorphous metal Zr_x Cu_1-x (x=0.3 and x=0.4), by measuring the relative change of…

Inter- and Intragranular Effects in Superconducting Compacted Platinum Powders
Alexander Schindler, Reinhard Koenig, Thomas Herrmannsdoerfer +1
Compacted platinum powders exhibit a sharp onset of diamagnetic screening at mK in zero magnetic field in all samples investigated. This sharp onset is interpreted i…
