Abstract

PURPOSE:To obtain a bistable type magnetic element having excellent characteristics, by holding an amorphous metallic film band of a specified composition under a shape of using time after it is subjected to adistortion-relief heat treatment under a shape different from that of using time, and by giving a high magnetic distortion which shows anistropies whose direction at the upper surface is different from that at the lower surface to the film band. CONSTITUTION:A beltlike magnetic film (thickness: 10-100mu, width: 1-10mm.) is manufactured from a material shown by the formula (where, M is metallic elements, such as Mo, Mn, etc., other than Fe, Co, and Ni; X is glass elements, such as Si, B, P, etc.; a and b and c indicate atomic ratios of 0.3-1.0 and 0-0.4, respectively; x, y, and z are values representing atomic % of 10-88, 0-30, and 10-38, respectively; a+b+c is 1, and x+y+z is 100), for example Fe80B20, Fe81B17Si2, etc., is produced by quenching and solidifying after the material is melted. Then, the film band is wound to a ring of 4-14mm. diameter and the film is subjected to a distortion relief treatment at a temperature between the curie point and the crystallizing temeperature. After the treatment, the film is quenched. After quenching, the film is straightened and shaped to a shape at the time of using by fixing both ends and so like. In this way, an element which has characteristics which generate pulses of small nucleus forming magnetic field and wide and sharp exciting frequency and so like, and which is suitable for making optionally shaped sensors, frequency measuring devices, etc., is obtained.
