Abstrakt: Silicon doped with Er, Gd, or Ho to concentrations from 3 × 1015 to 2.3 × 1017 cm–3 was found to exhibit a negative magnetoresistance at 77 K, which is a manifestation of the giant magnetoresistive effect. This effect is due to the alignment of the magnetic moments of rare-earth clusters along the applied magnetic field, which reduces the scattering of charge carriers. [ABSTRACT FROM AUTHOR]
