The giant magnetoimpedance (GMI) effect for NiFeB layer with thickness of 3[mu]m on CuBe core with diameter of 100[mu]m has been studied. After adding an insulator layer, the maximal GMI ratio of CuBe/Insulator/NiFeB composite wire is much higher than that of CuBe/NiFeB composite wire, and can reach to about 250% at the frequency range of 500kHz-1MHz. The results are explained in terms of difference of magnetic structure and different frequency dependence of resistance and reactance of the two kinds of composite wires.
