PURPOSE:To improve the position accuracy and transfer accuracy of paired Bloch lines by forming a heating resistor of a shape corresponding to a magnetic domain on the surface of a magnetic thin film and providing a power application means to the heating resistor. CONSTITUTION:A magnetic garnet thin film 4 is provided on a nonmagnetic garnet substrate 2. A film of HfB2 is formed on the entire face of the thin film 4 and patterning is applied to the film 20 so as to leave only a flat shape part slightly larger than the flat shape of an objective stripe magnetic domain 6. Then electrodes 22, 23 are formed by patterning on a prescribed location of the thin film 4 and the heat resistor 20. Then an upward bias magnetic field Hb is applied externally, a pulse voltage is applied between the electrodes 22 and 23 to give a pulse current to the resistor 20. Thus, a magnetic bubble 7 is generated on the thin film 4 corresponding to any of the maximum point of two temperatures and the stripe magnetic domain 6 corresponding to the heating resistor at the position formed in advance with the resistor 20 is formed accurately and stably.
