The magnetic properties of ultrathin Fe_(84)B_9Nb_7 nanocrystalline ribbon alloy with the thickness of 7-14 ㎛ were investigated. It was found that the effective permeability at the frequency over 100 ㎑ increased with decreasing ribbon thickness. Moreover the core loss decreased considerably with reduction of the ribbon thickness. The effective permeability at 1 ㎒ and the core loss at 1 ㎒ and 0.1 T for Fe_(84)B_9Nb_7 alloy with the thickness of 7 ㎛ were 3,700 and 2.7 W/cc, respectively. The reduction of thickness to less than 10 ㎛ was found to be very effective in obtaining high permeability and low core loss in the ㎒ frequency range. It was considered that the improvement of magnetic properties in the high frequency range was due to the reduction of the eddy current.
