Title:
非晶質磁性合金
Document Type and Number:
Japanese Patent JP5069408
Kind Code:
B2
Abstract:

To provide a soft magnetic amorphous alloy having over-cooling liquid zone and also having excellent amorphous formability and soft magnetic characteristic by selecting and optimizing the alloy composition in the amorphous magnetic alloy.

The amorphous magnetic alloy is shown with composition formula: Fe100-w-xLwBx[wherein, Fe is the main component with inevitable impurities, L is one or more elements selected from Y, lanthanoid (La,Ce,Pr,Nd,Pm,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu) and misch metal (MM), and shown with 1 atm%≤w≤8 atm%, 14 atm%≤x≤26 atm%] and has excellent amorphous formability and soft magnetic characteristic and has over-cooling liquid zone. Amorphous bulk member contains the amorphous magnetic alloy powder.
