摘要
The soft magnetic properties of ring-shaped (Fe0.75B0.20Si005)(96)Nb-4 cast bulk metallic glass (BMG) with thickness of 0.3-1.0 mm have been investigated. The BMG specimens exhibit high relative permeability of (9-29) X 10(3) at 0.40 A/m and 50 Hz and low coercivity of 4.0 A/m. The core losses of the 0.3 mm thick BMG specimen are lower than those of commercial Fe-6.5 mass% Si steel (6.5Si) with the same thickness, and are comparable to those of the 0.10 mm thick 6.5Si. The low core losses of the BMG originate from the low coercivity and high electrical resistivity.
