Description

Y3Fe5O12, Y3Al5O12 and Gd3Ga5O12 single crystal garnets were implanted with 1017 iron.cm-2. Complementary techniques: CEMS, TEM and XRD at glancing angles have allowed to follow the behavior of implanted iron during thermal annealings. For Y3Fe5O12 large α-Fe2O3 particles are formed after annealings and at 12000C occurs a low temperature regime of the Morin transition at room temperature. For Y3Al5O12, due to aluminium substitution in the precipitates, the Morin transition is only detected after an annealing at 13000C whereas in Gd3Ga5O12 no Morin transition is observed. (orig.)
