Measuring bubble-bubble interaction in gap tolerant circuits

The paper is concerned with a method for measuring Hb-b, the field of bubble-bubble interaction in the entire operation margins of bubble devices. Measurements of Hb-bare given for asymmetrical chevron, tapir, and half-disk patterns with various code sequences and interelement gaps. In the main part of the operation margin of Hbthe dependence Hb-b= f(Hb) is shown to be linear for practically all code sequences. The method helps reveal certain features of bubble-bubble interaction in the I-1 pattern.
