Özet

Structural, magnetic and giant magnetoresistance properties of the electrochemically deposited FeCo(Cu)/Cu multilayers at the various cathode potentials for magnetic layers were investigated. The cathode potentials were -1.8, -2.0, -2.5 and -2.8 V for magnetic layers and -0.3 V for non-magnetic layers with respect to a saturated calomel electrode. The multilayers have a face-centred-cubic structure. The obtained composition was found to be close the nominal composition at -2.8 V cathode potential. The highest giant magnetoresistance value (16.50 %) was obtained in the multilayer produced at -1.8 V. The highest sensitivity was found in the multilayer produced at -1.8 and -2.8 V.
