Magnetic properties, special features of magnetic anisotropy, magnetic domain structure, and huge magnetic impedance of permalloy/copper/permalloy film elements fabricated by the method of ion-plasma sputtering are investigated. Elements with different plane geometry of layers are analyzed. In the first case, all layers of the element have identical sizes of 10 × 0.5 mm, and in the second case, the width of the copper layer is narrowed down to 0.2 mm. The magnetic properties and the magnetic impedance of the examined film elements allow them to be used as detectors of low magnetic fields. The elements of the first type are more adapted to low excitation current frequencies (up to 150 MHz), and those of the second type are more adapted to high frequencies (above 150 MHz).
