“…Later work produced remarkably effective bubble lattices which could be used as modulated diffraction gratings (Papworth 1974, Muller er a1 1975, and interesting suggestions for magneto-optic memories, which would combine magnetic garnet films and photo-conductive layers (Krumme and Schmitt 1975). More recently, very effective electrophotographic printing techniques have been developed as a result of magnetic bubble research (Hill 1984) while Hansen et al (1984) have demonstrated a striking display device.…”

“…An example of all these problems coming together can be seen by reference to the paper by Hill (1984) describing a light switching array for electro-photographic printing. This used a magnetic garnet film with a composition close to Gd2BiFe,.4All.4Ga0.20,2, having an excellent figure of merit: nearly 50" at a wavelength, well into the orange, T H Q'Dell of 570nm.…”

The invention of a number of interesting magnetic bubble domain devices over the past eighteen years, for computer memory, data-flow data processing and optical image processing, has brought many new and interesting problems to the attention of physicists. These problems, in materials, particularly crystal growth, in magnetic domain dynamics, in the physics of ion implantation, in complex magnetic field calculations and in magneto-optics are reviewed and discussed. It is concluded that we have here a particularly significant example of the interaction between technology and science.

The research into insulating ferrimagnetic garnets has gained enormous momentum in the past decade. This is partly due to the improvement in the techniques to grow high-quality ultrathin films with desirable properties and the advances in understanding the spin transport within the ferrimagnetic garnets and through their interfaces with conducting materials. In recent years, we have seen remarkable progress in controlling the magnetization state of ferrimagnetic garnets by electrical means in suitable heterostructures and device architectures. These advances have readily placed ferrimagnetic garnets in a favorable position for the future development of insulating spintronic concepts. The purpose of this article is to review recent experimental results of the current-induced magnetization control and associated phenomena in ferrimagnetic garnets, as well as to discuss future directions in this rapidly evolving area of spintronics.

We report the fabrication of a crystal or an amorphous micropatterned ridge buried in a magnetooptic film by use of the selectedarea sputter epitaxy. The ion-beam bombardment on the deposited amorphous film was found to be influential in crystal growth on an amorphous region. We successfully formed a crystalline single patterned-ridge with 3 µm width, whose cross section was inverted-trapezoidal, into an amorphous region, and an amorphous single patterned-ridge, whose cross section was triangular, into a crystal region.
