A novel stripe domain stabilization method for Bloch line memory is proposed to simplify the stripe initiation procedure and facilitate the chip fabrication process. In this method, stripe domains are stabilized by stray magnetic fields from thermomagnetically written domain patterns (WDPs) in a perpendicular magnetization film with high coercivity, deposited on a layer supporting stripe domains. Chip organization has been studied by experiments and numerical simulation using a 5 μm bubble material. The stripe domain heads were stretched using the conductor current with the optimized WDP of 3.5 μm width and 12 μm period. Bit by bit propagation of vertical Bloch line pairs was confirmed by numerical simulations for the chip with the WDP having a fish-bone shape, which can perform both stripe stabilization and bit confinement.
