PROBLEM TO BE SOLVED: To provide a polycrystal structure film and a method for forming the same capable of surely contributing to reduction in the size of a magnetic grain. SOLUTION: Insular magnetic grains 32 are surrounded by a first separation layer 33. Insular magnetic grains 36, 38 are formed on crystal layers 35, 41. The crystal layers 35, 41 function to arrange the orientation of the magnetic grains 36, 38. Amorphous layers 34, 39 exist between the crystal layer 35 and the magnetic grains 32 or between the crystal layer 41 and the magnetic grains 36. The amorphous layers 34, 39 suppress interface reactions between the magnetic grains 32, 36 and the crystal layers 35, 41 in a forming process. The orientation of the magnetic grains 32, 36 is thereby sustained surely. COPYRIGHT: (C)2008,JPO&INPIT
