Swift heavy ion (2 GeV ¹⁸¹Ta) irradiation-induced amorphization and temperature-induced recrystallization of cubic pyrochlore Gd₂Ti₂O₇(View the MathML source) are compared with the response of a compositionally-similar material with a monoclinic-layered perovskite-type structure, La₂Ti₂O₇ (P2₁). The averaged electronic energy loss, dE/dx, was 37 keV/nm and 35 keV/nm in Gd₂Ti₂O₇and La₂Ti₂O₇, respectively. Systematic analysis of the structural modifications was completed using transmission...[Show more]
