✦ Synopsis

It is shown by a NMR analysis of AI nuclei and Adiabatic Demagnetisation that in a pure crystal of AI203 (sapphire) the heat capacity due to the Quadrupolar Interaction is weakly coupled to the phonon bath at low temperatures. Therefore, it does not prevent this type of absorber from being an excellent candidate for bolometric applications.
