Thermodynamic and kinetic fragility of Freon113: the most fragile plastic crystal
A. Vispa, M. Romanini, M. A. Ramos +6
We present a dynamic and thermodynamic study of the orientational glass former Freon113 (CCl2F-CClF2) in order to analyze its kinetic and thermodynamic fragilities. Freon113 displa…
Do Two-Level Systems and Boson Peak persist or vanish in hyperaged geological glasses of amber?
Tomás Pérez-Castañeda, Rafael J. Jiménez-Riobóo, Miguel A. Ramos
In this work we extend, review and jointly discuss earlier experiments conducted by us in hyperaged geological glasses, either in Dominican amber (20 million years old) or in Spani…
Low-temperature specific heat of graphite and CeSb2: Validation of a quasi-adiabatic continuous method
T. Pérez-Castañeda, J. Azpeitia, J. Hanko +3
We present the application of a fast quasi-adiabatic continuous method to the measurement of specific heat at 4He temperatures, which can be used for the study of a wide range of m…
Are the calorimetric and elastic Debye temperatures of glasses really different?
Miguel A. Ramos
Below 1 K, the specific heat Cp of glasses depends approximately linearly on temperature T, in contrast with the cubic dependence observed in crystals, and which is well understood…
