Abstract: PURPOSE: To avoid embedding due to dropping of grown crystal and avoid adverse influence on grown crystal due to occurrence of latent heat due to drastic solidification of melt by giving solidifying cause to the melt and solidifying the melt when grown single crystal is gradually cooled in a state separated from the melt face. CONSTITUTION: β-BaB2 O4 single crystal excellent in crystallinity is obtained in good yield by a pulling-up growing method from the melt having BaB2 O4 composition, especially not using flux. BaCO3 is mixed with B2 O3 in a molar ratio of 1:1 as starting raw materials and the mixture is housed in a platinum crucible 2 and the single crystal is grown using a seed crystal 7. After finishing the growth, the single crystal is pulled up to the position which is about 5mm separate from the liquid level of the melt and cooling of the single crystal is started by rotating the crystal in a state in which grown single crystal 8 is pulled up immediately above the melt 1. At the point of time when melt temperature is lowered to a temperature which is about 100 deg. lower than a temperature at which the growth is finished, a part of the seed crystal 7 is folded and the grown single crystal 8 is dropped, but the melt is already solidified and the single crystal is not embedded therein.

Abstract: PURPOSE:To stabilize recording and movement of recording bits stably by forming a part having a different magnetic energy in a soft magnetic film magnetized easily vertically to the film surface by ion implantation and generating a cylindrical magnetic domain along the boundary part between this part and a part different in magnetic energy. CONSTITUTION:An area 21 having a different magnetic energy is formed in the soft magnetic film magnetized easily vertically to the film surface, to which a bias magnetic field is so applied that magnetization is vertical to the film surface and is directed to one direction, by ion implantation. A magnetic bubble (b) of the cylindrical magnetic domain is formed in the left upper corner or the like of the boundary part between the area 21 and an area, where ions are not implanted, along the boundary part by irradiation or laser light or the like to perform thermal magnetooptic recording. Then, the bubble (b) is recorded stably in this boundary part because force Fc applied to the bubble (b) is a prescribed value. Similarly, the bubble (b) is moved stably along boundaries of the area 21 to move recording bits stably.

Abstract: PURPOSE:To stabilize the writing position by setting the recording position by making use of the force acting on a magnetic bubble which is produced by the change of the magnetic energy at the areas of different levels of film thickness. CONSTITUTION:A thin film of YSmGaFeGe garnet is formed on a garnet substrate 1a by an LPE process to obtain a film 1b containing a soft magnetic film surface magnetized vertically and easily. Then square hollow parts 21 are arrayed with a prescribed pitch on the surface of the oxide film 1b by a photolithography process, and therefore a stage part 22 is formed at the edge part of each hollow part 21. An argon ion laser is used as a recording light source and then stopped down to form a 1.0mum spot on the film 1b, and the recording is performed with 5.0mus pulse width. Then the writing pulse light is irradiated within a 1/4 circle centering on the diagonal line passing through a point A of the part 21 for a circle which is drawn with an about 3.2mum radius from the point A within a distance of the 1.2mum radius of a bubble (b), i.e., from adjacent side walls 22a and 22b of the part 21. Thus it is confirmed that the bubble (b) is stably generated at the point A.

Abstract: PURPOSE:To prevent the variation of offset voltage due to a humidity change by forming two ferromagnetic films having an anisotropic magnetoresistance effect so as to mutually cross at right angles on a substrate. CONSTITUTION:The magnetoelectric transducer 1 is formed by the folded line- shaped ferromagntic substances A, B, which are formed by evaporating a 80Ni- 20Co alloy to the insulating substrate 7, such as slide glass, a photographic dry plate or the like, to which interface purging treatment is executed, in the thickness of 600-1,000Angstrom and removing unnecessary sections through etching, an output terminal 4 shaped to the approximately intermediate position of the ferromagnetic substances A, B, and current terminals 2, 3 formed at other end sides of the ferromagnetic substances A, B. The ferromagnetic substances A, B consist of rectilinear sections 8, 9 functioning as main current paths and bent sections 10, 11 mutually connecting the rectilinear sections, and the rectilinear sections 8, 9 are mutually crossed at right angles.
