摘要： According to the present invention, in the PFC (planar flow casting) method, He gas at room temperature is blown onto the surface of a cooling roll at a flow rate of 0.1 to 5 liters/min.multidot.cm.sup.2 through a He gas blow nozzle provided upstream of a molten alloy (a puddle) ejected through a molten alloy ejection nozzle onto the surface of the cooling roll at a distance from the ejection nozzle, the distance from the surface of the cooling roll and an angle of inclination of the nozzle within respectively specified ranges, thereby forming a He gas atmosphere around the puddle, and a thin strip is dragged out of said puddle. This enables a thin amorphous alloy strip having a very small thickness and a smooth surface free from significant uneven portions and pores to be easily produced at a low cost without use of any vessel for regulating the atmosphere or an apparatus for heating the blown gas.

The blind bodies 2a, 2b are coupled in a row by serially coupling each slat 1 in each blind body 2a to a corresponding slat 1 of adjacent blind body 2b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2a, 2b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2a, 2b form openings in the magnetic shield structure. Preferably, three or more magnetic blind bodies 2 are coupled in a row so as to form a closed magnetic path. The blind bodies 2a, 2b may be stacked side by side in such a manner that the blind core plane Fa, Fb are parallel to each other and orientation of the slat central axes in each blind body 2a, 2b being selected so as to optimize attenuation of magnetic field across the magnetic shield structure.
