Abstract: PURPOSE:To provide the memory which allows the formation of both magnetic films on the same element and can be easily produced by constituting intra- surface magnetized film patterns and perpendicularly magnetized film patterns by varying the coercive forces thereof. CONSTITUTION:Plural striped magnetic domains 16 are parallel formed on a magnetic thin film 2 having perpendicular magnetic anisotropy and the perpendicular Bloch lines formed on the magnetic walls of such striped magnetic domains 16 are determined as a memory information unit. Guide magnetic domains 17 are formed on one end side in the extension direction of the striped magnetic domains 16. The striped magnetic domains 16 and the guide magnetic domains 17 are stabilized by the perpendicularly magnetized film patterns 7 laminated on the magnetic thin film 2. The recording bit positions on the striped magnetic domains 16 are stabilized by the intra-surface magnetized film patterns 4. The coercive forces of the intra-surface magnetized film patterns 4 and the perpendicularly magnetized film pattern 7 are varied. Both the magnetized films are stably magnetized in this way.

Abstract: PURPOSE:To securely control the expansion/contraction of stripe magnetic domains by stabilizing the stripe magnetic domains and guide stripe magnetic domains by means of vertical magnetized film patterns laminated on a magnetic thin film. CONSTITUTION:The guide stripe magnetic domains 2 restrict the expansion of the stripe magnetic domains 1 which are arranged in parallel in one direction. The expansion of the stripe magnetic domains in one direction is guided by magnetic field potential between the guide stripe magnetic domains provided on the side of one end of the adjacent stripe magnetic domain and it is restricted to the prescribed direction. The stripe magnetic domains 1 and the guide stripe magnetic domains 2 are stabilized by the floating magnetic fields of the vertical magnetized film patterns 4, 5 and 6 and the shapes of the guide stripe magnetic domains are held as they are without being cut by a local magnetic field for cut at the time of reading and writing. Thus, the expanding direction of the stripe magnetic domains can securely be controlled by the guide stripe magnetic domains.

Abstract: PURPOSE:To attain sure readout, replicate, erasure and write by surely generating a negative Bloch line to the chopping end of a minor loop side after the chopping. CONSTITUTION:A minor loop part 1 and a major line 2 are provided to a perpendicular magnetic film 11. Plural minor loops ML having a negative vertical Bloch line -VBL are arranged to the loop 1. A chopping means 4 comprising chopping conductors 4a, 4b is arranged to the side of the line 2 of the loop. The conductors 4a, 4b are energized reversely to generate a perpendicular magnetic field between the conductors in a direction integrating the opposed magnetic walls of stripe magnetic domains constituting the loop ML. Thus, the absolute value of the vertical or horizontal magnetic field component in the magnetic field distribution of the overall magnetic field formed by the conductors 4a, 4b has at least one maximum peak in all the depth in the film 11. Thus, the -VBL is generated.

Abstract: PURPOSE:To minimize the puch-through phenomenon of a magnetic wall and to secure a stable memory action by forming an area with the in-surface magnetic anisotropy on the surface layer part of a chopping action area chopping the tip of a strip magnetic domain. CONSTITUTION:Ions are selectively inplanted in strip-like areas orthogonally intersecting with the both tip areas of the strip magnetic domain 1 in a ferromagnetic film 10, the magnetic domain 1 and a magnetic wall 4, and the magnetizing direction is turned down in the film surface to form in-surface magnetizing areas 11, 12 and 13. The areas 11 and 12 where the both tips of the magnetic domain 1 are positioned are provided with two chopping conductors 2 and 3 for reading information, becomes a chopping action area. Each strip-like area 13 is set at an interval corresponding to a pair of vertical Bloch lines 8 formed on the magnetic wall 4, thereby stabilizing the bit position of information. The punch-through phenomenon appearing in a chopping action together with the movement of the magnetic wall can be minimized.
