Magnetic properties of amorphous FeCoSiB alloys annealed in rotating magnetic field
Two kinds of magnetic annealing are studied for zero-magnetostriction (FeCo)76.5 + 6.2z (SizB1 − z)23.5 − 6.2z alloys having different [Si]/([Si] + [B]) ratios (z = 0−0.5) and the same saturation induction of 10.5 kG. By static field annealing, the value of initial permeability μ1 at 1 kHz falls below 1000 for all the alloys. By rotating field annealing, μ1 for z = 0.4 exceeds 10 000. The highest μ1 alloy of (Fe0.067Co0.933)79 (Si0.4B0.6)21 has μ1 = 12 000, Hc = 11 mOeandBr = 3.8 kG. The preferable [Si]/([Si] + [B]) ratio z for higher μ1 (above 10 000) is between 0.35 and 0.5.
