ABSTRACT:
A garnet single crystal film wherein part of iron ions at tetrahedral positions and octahedral positions are replaced by an appointed amount of the other ions is by far superior to prior art garnet films in that its saturation magnetization (4.pi.Ms) and its exchange stiffness coefficient (A) can be independently controlled to a desired value and a magnetic bubble domain having a small diameter can be easily formed.
