Exploratory Development of Magnetic Bubble Domain Material for Application in Air Force Solid State Mass Memory Systems.
Abstract
Tests performed on bubble domain materials indicate that they are resistant to mechanical stresses of 50g. In a study of FMR and bubble domain wall mobility, it was found that the mobility is quite temperature sensitive over the range of interest, that FMR gives an upper bound but not a true value of mobility and that the exchange constant is about 0.6 of the normally assumed value for bubble domain compositions. An investigation aimed at selecting a composition to meet Air Force computer memory goals indicates that lower wall energy materials will have to be employed to reach high data rates. (Author)
