Abstract :
Giant magnetoresistance (GMR) has been observed in magnetically optimized AlNiCo/sub 5/ and FeCrCo bulk alloys with amplitudes sizes as much as 3% at 300 K and 5% at 10 K. In contrast, homogenized FeCrCo samples show the anisotropic magnetoresistance. The field dependence of the GMR amplitude cannot be scaled by a simple function of magnetization due to a strong field dependence beyond saturation.
