Title:
FE-GROUP SOFT MAGNETIC METAL-GLASS ALLOY
Document Type and Number:
Japanese Patent JP3710226
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a Fe-group metal-glass alloy having a soft magnetic property at room temperature and having a high specific resistance, by causing the temperature gap of a supercooling liquid expressed by the crystallization start temperature and the glass transition temperature to be not less than a specified temperature, and causing the specific resistance to be not lower than a specified value.
SOLUTION: A Fe-group metal-glass alloy has a temperature gap ΔTx of a supercooling liquid expressed by a formula ΔTx=Tx-Tg represents the crystallization start temperature and Tg represents the glass transition temperature) which is not less than 35K, and a specific resistance of not lower than 1.5μΩm. This Fe-group soft magnetic metal glass alloy contains other metallic element and semi-metal element than Fe. Alternatively, this Fe-group soft magnetic metal glass alloy contains at least one or more, selected from P, C, B and Ge as semi-metal elements, or contains at least one or more of P, C, B and Ge as semi-metal elements and Si. Thus, a bulk-like Fe-group soft magnetic metal glass alloy which has a high saturation magnetization, a low coercive force and a high permeability may be provided.
