摘要
In Refs.[1] and [2], the superior magnetic properties have been reported for theexpensive synthetic ultra-microcrystalline Fe<sub>73.5</sub>Cu<sub>1</sub>Nb<sub>13</sub>Si<sub>13.5</sub>B<sub>9</sub> and Fe<sub>73.1</sub>Cu<sub>12</sub>Nb<sub>3.2</sub>Si<sub>12.5</sub>B<sub>10</sub>alloys. Partly replacing the expensive Nb by cheap Mo, we developed a new material,which was made into ribbons with the thickness of 28 μm and width of 3.0cm.
