Progress toward the Crosstie Memory VII.
Abstract
This is the seventh annual technical report of progress toward the crosstie memory and it emphasizes work done during the past year. Progress has proceeded to the point where short shift registers have been demonstrated at Sperry Univac, St. Paul, MN with data in, and data out, without the aid of Bitter solution. This is a significant step forward because the Bitter solution was known to alter the drive fields making the transition to operation without its use uncertain. Meanwhile, at NSWC, the effort has become more basic as we search for simpler propagation schemes, and methods for locking the domain wall or shift register track in place. Several experiments have been carried out in which the substrate has been etched before the permalloy is deposited. These experiments have provided several new insights as to how the memory may in the future be simplified. (Author)
