<P>PROBLEM TO BE SOLVED: To provide a Co-based metallic glass alloy which can exist stably as metallic glass and can exhibit excellent magnetic properties in a region from low frequency to high frequency, a high-performance magnetic core composed of the Co-based metallic glass alloy, a high-performance electromagnetic transducer having the magnetic core and a clock. <P>SOLUTION: An electromagnetic transducer 2 has a magnetic core 1 and a conducting wire (coil) 43 wound into a plurality of layers around a winding part 40 of this magnetic core 1. The magnetic core 1 is composed of a Co-based metallic glass alloy having a composition which contains Fe, B, Si and Nb and in which the contents of Fe, B, Si and Nb are made to, by atom, 2 to 8%, 23 to 27%, 1 to 3% and 0.5 to <4%, respectively. <P>COPYRIGHT: (C)2008,JPO&INPIT |
