Properties of cobalt/copper and cobalt/palladium multilayers.
The physical properties of Co/Cu and Co/Pd magnetic multilayers have been studied. The Co/Cu multilayers were prepared by sputtering, while the Co/Pd multilayers were made by sputtering and molecular beam epitaxy (MBE). Various x-ray diffraction techniques have been used to study the structure of …

Sol-gel processing of RxY3-xAlyFe5-yO12 magneto-optical films
… research was the fabrication of thin films with magneto-optic (MO) properties. Accomplishment of this task was achieved via sol-gel processing of rare-earth and aluminum substituted yttrium-iron garnet (RxY3-xAlyFe5-yO12, R,Al:YIG), where R= Bi, Gd, Er, Ho. Detailed are the processing conditions, …
