Abstract

PURPOSE:To extend and contact bubbles precisely and transfer them effectively by providing the entitled device with a thin film magnetic resistance detecting part and a hairpin-type conductor with which the detector is surrounded. CONSTITUTION:When a material with high magnetic permiability is used for a detecting part 2, the detecting part itself is magnetized and magnetic field grade is applied to synthetic potential. Namely, the potential becomes the smallest in transfer line patterns 39, 40. Since the bias magnetic field is weakened near the patterns, 39, 40, extended bubbles are contracted into the transfer line pattern hole 40. When the extended bubbles are contracted as bubbles, the force to be adsorbed to a permalloy of the detecting part 2 is weakened and the bubbles can be transferred completely only by driving current 16, 13, 14 and 15. Thus, the bubbles are transferred successively like patterns 40, 41 without stopping them in the position of the detecting part like the ordinary method.
