Abstract

The H⁺-ion treatment effect on TlH₂PO₄, a KH₂PO₄ (KDP)-type ferroelectrics, was studied by nuclear magnetic resonance (NMR) and AC dielectric constant measurements. A sample of TlH₂PO₄ was irradiated by 1-MeV H⁺ ion beams to a dose of 10¹⁵ ions/cm². The change in the NMR relaxation behaviors after the irradiation was attributed that in the hydrogen-bond geometry, presumably affecting the order-disorder proton dynamics. A prominent decrease in the dielectric constant was also observed after the irradiation. The macroscopic and microscopic changes due to the irradiation are discussed in the light of the proton dynamics.
