Investigation of radiation-stimulated processes in epitaxial yttrium-iron garnet films

Displacement Defect Formation in Complex Oxide Crystals under Irradiation

“…At such fluences an increase of the crystal lattice parameter as well as a decrease of the saturation magnetization and Curie temperature take place. In a number of papers [35,38,39,41] it was shown convincingly that a disordering process is responsible for these changes that occur as losing of long-range order in microareas that have been affected by the atom±atom displacement cascades. The rest bulk remains of the garnet structure.…”

“…Y 3 Fe 5 O 12 Much efforts were spent to investigate the neutron irradiation influence on structural and magnetic properties of poly-and single crystals of yttrium iron garnet (YIG), related iron garnets [26 to 38] and epitaxial iron garnet films [1,39,40] as well. Essential changes of iron garnet parameters were observed by different authors at neutron fluences higher than 10 18 cm ± ±2…”
