Abstract

Electrotransport properties of Ge:(Mn, Al)/GaAs nanolayers deposited from laser plasma at a reduced temperature of 150°C have been studied along with those of the same samples after an additional 15-minute thermal vacuum annealing at 400°C. There has been found an asymmetry of the current-voltage characteristic (CVC) in the longitudinal current transport of such layers indicating spin polarized carriers, as well as significant nonlinearity and hysteresis up to 2% and 1%, respectively, both at room temperature and at 77K for relatively low current densities of 10
