... mode condenses at the zone boundary . In three dimensions and with about 5 atoms per unit cell the soft mode physics is of course much more complex . Especially the crossing of phonon branches and mixed second - order and first - order ...

... mode is at v = 123 cm 1 in YAG . In DyAG , HOAG , and ErAG where the rare earth ion substitutes for Y , this mode shifts to 95 cm - 1 . It further shifts to 85 cm - 1 for ErGaG and YbGaG . This lowest mode in YAG is probably an external ...
