Magneto-impedence (MI) were measured in amorphous Co_(66)Fe₄NiB₁₄Si15 ribbons at 100 ㎑ as a function of the angle from ribbon axis. The samples were prepared using etching method, with the angle deviated from ribbon axis, 0˚, 30˚, 45˚, 60˚ and 90˚. The MI measured in 60˚sample increased with the increasing magnetic fields. The dip in profile appears at H=0 above the angle of 30˚. The maximum values of MI and their dips are increased with the cutting angle, but the maximum value of MI decreased at 90˚. The increase of MI with the angle was analyzed in terms of the transverse magnetic permeability.
