Magnetoresistance and magnetic hysteresis in NiFeCo/Cu soft magnetic multilayers with a fixed number of bilayers (six) and magnetic and spacer layer thickness but varying composition has been studied. The highest value of the transverse GMR obtained is 6.8% in a saturation field of ≈40 Oe at room temperature. Very high sensitivity, around 1%-2%/Oe and unconventional easy-axis hysteresis and GMR loop shapes have been observed. The analysis of the GMR effects and the associated hysteretic behavior by using a model that includes biquadratic exchange coupling suggests that the samples are composed of at least two distinctively different parts.
