Swift-heavy ion irradiation response and annealing behavior of A2TiO5 (A = Nd, Gd, and Yb)

(Left) Crystal structure of orthorhombic (top) and cubic (bottom) A2TiO5 compounds with space group Pnma and Fm-3m, respectively. (Right) Representative XRD patterns of orthorhombic and cubic A2TiO5 irradiated with 2.2 GeV Au ion irradiation (λ = 0.4967 Å). All compounds exhibit crystalline-to-amorphous phase transition.334
