| Abstract: | The annular cores were prepared with amorphous ribbons which nominal composition is Fe73.5Cu1Nb3Si15.5B7（at.%）with thickness of 18 μm,22 μm and 26 μm.The magnetic properties of the cores that annealed at 560 ℃ for 1 h was analyzed.It was found that the cores made from thinner ribbon show significant lower core loss.And the cores made by the ribbons with thickness of 18 μm and 22 μm show similar properties on static magnetic properties,core loss property,inductance and impendence properties in comparison with VAC＇s cores.Cores made by ribbon with thickness of 18 μm show higher initial permeability at high frequency and lower core loss than VAC＇s cores. |
