Magnetization reversal process and nonlinear magneto-impedance in Cu/NiFe and Nb/NiFe composite wires

“…At higher AC current amplitudes the magnetization reversal of the sample takes place. This process is accompanied by the appearance of a nonlinear voltage response at the sample ends and in the pick-up coil wound around the sample [1,7,8]. Due to the strong magnetic field dependence, this nonlinear magneto-impedance effect is also promising for possible technological applications.…”

Magnetic Properties and Magnetoimpedance of Electroplated Wires

“…It has been established that the high harmonics can show larger variation under application of an external magnetic field than the fundamental one. In order to explain the high sensitivity of the harmonics various theoretical models were proposed [2][3][4]. It was shown that for FeCoNi electroplated wires the strong nonlinear effects are the consequence of the high value of the transverse susceptibility at the points of re-orientational phase transitions in the magnetic layer and that the high-order magnetic anisotropy may play a key role [3][4].…”

“…In 1996 Beach at el [2] has re-discovered these materials for technological applications (low magnetic field sensors) and basic studies of non-linear processes. Non-linearity of the magnetization processes was proved for different compositions of the electroplated [3][4] and composite [5] wires by Fourier analysis of the induced voltage (the high harmonics generation) and nonlinear dependence of the induced voltage on the driving current amplitude.…”

Giant Magnetoimpedance in Ti/CoP Plated Wires

“…Most of previous published papers treated magnetoimpedance on plated wires with a constant magnetic thickness. [9][10][11][12] Up to now no detailed experimental data about the influence of magnetic layer thickness on the GMI effect were given yet, except one report on Cu/CoP wires with CoP thickness D of 3, 4 and 7 mm.…”

“…Besides of the uniform wires, ribbons and films, [3][4][5][6][7][8] this effect has been observed in inhomogeneous structured materials such as non -magnetic conducting wire plated with magnetic layers and some sandwich films. [9][10][11][12][13][14][15][16][17][18] Large GMI effect occurs at a relative low frequency in BeCu/NiFe, 9) BeCu/CoFeNi, 10) Ag/NiFe 11) and Cu/CoP 12,13) plated wires. Most of previous published papers treated magnetoimpedance on plated wires with a constant magnetic thickness.…”
