Özet

This study examines a linear variation of the specific heat C-P with the frequency shifts 1/nu(partial derivative nu/partial derivativeT) for the Brillouin frequencies of the L-mode [010], [001] and [100] in the ferroelectric phase of NaNO2 according to our spectroscopically modified Pippard relation. We obtain this linear relationship for those modes studied and calculate dT(C)/dP in the ferroelectric phase of NaNO2. Our calculated values of dT(C)/dP for the [001] and [100] modes are in good agreement with the values given in the literature. (C) 2001 Elsevier Science B.V. All rights reserved.
