Relationship between microwave and lattice vibration properties in Ba(Zn1/3Nb2/3)O3-based microwave dielectric ceramics
Result description
The dielectric properties of ceramics, with x between 0 and 0.2 were studied at MW, terahertz (THz) and infared (IR) frequences at temperatures from 10 to 300 K. IR and THz spectra as well as the low-temperature MW dielectric measurements revealed a weakdielectric relaxation below phonon frequencies, possibly arising from charge caused by inhomogenous distribution of the B-site ions with differing valences

Vztah mezi mikrovlnnými vlastnostmi a dynamikou krystalové mřížky mikrovlnných dielektrických keramik založených na Ba(Zn1/3Nb2/3)O3.
Czech description
Dielektrické vlastnosti keramik byly studovány v mikrovlnné, terahertzové a infračervené oblasti při teplotách od 10 do 300 K. Pozorované slabé relaxace v mikrovlnné oblasti jsou způsobeny nehomogenní distribucí různěvalentních atomů v B polohách
