Nonlinear Magnetoimpedance Effect in FeCoNi Ferromagnetic Tubes [PDF]
Chinese Physics Letters, 2001 [EN] The very high (up to 820% of the magnetoimpedance ratio) and sensitive nonlinear giant magnetoimpedance effect has been studied in the FeCoNi magnetic tubes electroplated onto Cu(3%)Be nonmagnetic wire for frequencies from 1-10 MHz. Special annealing was carried out in order to induce the magnetic anisotropy.
