摘要

Studies of radiation damage in magnetoplumbite-type LaMgAlnO_(19) and CeMgAlnO_(19) are reported. Ion irradiation was conducted on ceramic composites containing a LaMgAl_(11)O_(19) phase at 500℃ with 10 MeV Au~+ ions and on ceramic composites containing CeMgAl_(11)O_(19) phase at 800℃ with 92 MeV Xe~+ ions. The radiation response of these similar LnMgAl_(11)O_(19) (Ln = La and Ce) hexaaluminate magnetoplumbite phases was evaluated using transmission electron microscopy (TEM) and X-ray diffraction (XRD). LaMgAl_(11)O_(19)was amorphized by 10 MeV Au ions with swelling of the structure within an approximate 2 urn radiation depth from the irradiation surface. CeMgAl_(11)O_(19) did not amorphize after 92 MeV Xe-ion irradiation, but ion track damage contrast is seen in approximately 5 urn of the irradiated depth. SRIM Monte-Carlo simulations of nuclear displacements correlate with the experimental results.
