Longitudinal relaxation of mechanically free KH₂PO₄ type crystals. Piezoelectric resonance and sound attenuation
Within the framework of proton model with taking into account the piezoelectric interaction with the shear strain ε₆, a dynamic dielectric response of KD₂PO₄ type ferroelectrics is considered. Experimentally observed phenomena of crystal clamping by high frequency electric eld, piezoelectric reso...

| description |
Within the framework of proton model with taking into account the piezoelectric interaction with the shear
strain ε₆, a dynamic dielectric response of KD₂PO₄ type ferroelectrics is considered. Experimentally observed
phenomena of crystal clamping by high frequency electric eld, piezoelectric resonance and microwave dispersion
are described. Ultrasound velocity and attenuation are calculated, peculiarities of their temperature
dependence at the Curie points are described. Existence of a cut-off frequency in the frequency dependence
of attenuation is predicted. |
