    The diagonal and off-diagonal nonlinear magnetoimpedance in amorphous ribbons with well defined magnetic anisotropy is investigated. Field- and stress-annealing are used to produce easy-ribbon-axis and hard-ribbon-axis anisotropy, respectively. The dependence of the first three harmonic components of impedance on applied magnetic field and dc bias current is discussed. A theoretical explanation of the observed behavior, based on the symmetry properties of nonlinear Landau-Lifshitz-Gilbert equation, is proposed.
