Abstract

Low frequency Raman and Brillouin scattering experiments in yttrium and lanthanide metaphosphate glasses have been carried out over a wide range of temperature from liquid helium to the glass transition temperature (T-g congruent to 900 K). Analysis of the Raman data together with complementary low temperature specific heat and ultrasonic velocityresults reveals that the temperature and frequency dependences of thequasi-elastic scattering and Boson peak and in addition the anomalouslow temperature specific heat, are in qualitative agreement with the predictions of the soft potential model.
