Rare-earth substitution in (BiYCa) sub 3 (FeSiGe) sub 5 O sub 1 sub 2 bubble films

The substitution of Sm, Tb, Gd, and Ho for Y in (BiYCa) sub 3 (FeSiGe) sub 5 O sub 1 sub 2 bubble garnet affects growth-induced anisotropy. A new film composition containing Sm, Tb, and Gd satisfies known material property specifications for 6- or 8- mu m period memory devices. It can be grown with...

Zusammenfassung:The substitution of Sm, Tb, Gd, and Ho for Y in (BiYCa) sub 3 (FeSiGe) sub 5 O sub 1 sub 2 bubble garnet affects growth-induced anisotropy. A new film composition containing Sm, Tb, and Gd satisfies known material property specifications for 6- or 8- mu m period memory devices. It can be grown with 45- 50 K supercooling.
