摘要

Basic soft magnetic alloy (Fe-based soft magnetic alloy containing Fe, Cu and M as essential components, wherein M is at least one component selected from the group consisting of Nb, W, Ta, Zr, Hf, Ti, and Mo) based soft-magnetic alloy. Desc / Clms Page number 2 Wherein the magnetic alloy has an alloy structure in which the microcrystalline grains having an average grain size of 100 nm or less have an area ratio of at least 50%. The magnetic core has (1) a residual operating magnetic flux density RTI ID = 0.0 Bb /RTI (2) a total control operating magnetic flux density Br of 2.0 T or more; And (3) a formula of Gr = 0.8 x (DELTA Br-DELTA Bb) / Hr (where Hr is 0.8 x (DELTA Br-DELTA Bb) + DELTA Bb) of 0.10-Which is the total control gain Gr defined by the total control gain Gr.
