ABSTRACT:
A magnetic bubble expander-detector circuit comprising a pattern of magnetic material, forming Chevron elements positioned over a bubble-supporting material to define a bubble expander-detector circuit. Each element of the pattern is spaced from the bubble material such that a gradient is formed in the spacing between the element and the bubble material in the direction of the expansion and detection. A rotating magnetic field of sufficient strength to magnetize the pattern is applied in the plane of the material and the gradient of the spacing causes the bubbles to move from one element to an adjacent element as the bubbles are expanded and ultimately detected by suitable detection devices. This invention is particularly characterized in that, with the combination of the pattern elements and the gradient spacing thereof, gaps between adjacent elements are eliminated.
