Thermoelastic properties ofAl: YIG ceramic systems

  • N. Sparvieri


Interferometric thermal diffusivity measurements and elastic constants obtained by ultrasonic techniques on Y3Fe5_ϰAlϰO12 (with ϰ 4 0, 0.4, 0.8, 1.1) ceramic samples are presented and discussed. The phonon mean free path is given as a function of ϰ using the Boltzmann transport equation.
