i, Mn contribute to the improvement of coercive force (BHC, summer Hc),
Co contributes to raising the Curie point, but if the total of these exceeds 0.10, the residual magnetic flux density (Br) decreases, so even if it is replaced, it should be 0.10 or less. If the amount is too large, the residual magnetic flux density (Br) will improve, but the coercive force (BHC, I Ha) will decrease, making it difficult to obtain an excellent maximum energy product ((BH)max), so α ≦0.85. On the other hand, if the amount of Fe is too small, the residual magnetic flux density (Br) will become low and the maximum energy product ((BH)max) will decrease, so 0.

It is necessary to satisfy 001≦γ, but if the amount of Zn is too large, the residual magnetic flux density (Br) will decrease, so γ≦0.05.
