Abstract
Iron garnet monocrystal layer having a uniaxial anisotropy for preservation and continuation of magnetic cylindrical single-wall domains produced therein, is improved in that an iron garnet film on a substrate, showing a mechanically produced uniaxial anisotropy, contains yttrium besides a single lanthanide element so that the difference between the lattices of the substrate and the film is 0.02-0.16. The film used for information storage has increased domain speed in a wide range of field strength. High density of bits is achieved.
