Dielectric relaxation studies in Cs2SO4
Artikel i vetenskaplig tidskrift, 2006

Dielectric measurements of Cs2SO4 show a distinct relaxation at low frequencies at several isotherms ( T < 651 degrees C). For example, the relaxation frequency is around 5.1 kHz at 376 degrees C and increases to approximately 1 MHz at 651 degrees C. The relaxation has an activation energy of 0.97 eV, which is in close agreement whit that of Cs+ transport. We suggest that the observed dielectric relaxation could be produced by the Cs+ jump and SO4- reorientation that cause distortion and change the local lattice polarizability inducing dipoles like CsSO4-.
