摘要：
In this paper, the influence of annealing temperature on AC magnetic property of Fe15.38Co61.52Cu0.6Nb2.5Si11B9 nanocrystalline alloy is investigated, and the possible reasons for better high-frequency soft magnetic properties are analyzed. The resistivity decreases as annealing temperature increases. The value of mu'f(0) is not in direct proportion to saturation magnetization M-5 because of irregular variation of the gyromagnetic ratio with annealing temperature. At annealing temperature T-a = 873 K, the alloy has the largest quality factor and relaxation frequency, i. e., Q((1 MHz)) = 23.1 and f(0) = 25.02 MHz.
