| Abstract |
| Effective permeability and core loss have been investigated for (Co_(0.94-x)Fe_(0.06)M_x)_78 Si₄B_(18)(M = Cr, Ta, Mo) amorphous alloys in order to clarify soft magnetic properties at high frequencies. At the field of 10 mOe, effective permtabilities are large (e.g. 15,000) at 10 Hz, and decrease drastically with increasing frequency. Decrease of initial permeability due to the increase of frequency is minute at frequencies lower than 100 kHz. The initial permeability increases with the increase of M contents. The core losses of the alloys studied are smaller than that of a permalloy, and are the lowest when M=Cr, higher when M=Ta and the highest when M=Mo. |
