Abstract
We report an electron spin resonance study of Ge nanowires doped with chromium. The Ge0.99Cr0.01 nanowires contain both diluted Сr3+ and Сr2+ ions and a large amount of Cr-based nanoclusters revealing spin-glass properties at T<60 K. The observed antiferromagnetic resonance at low temperatures is attributed to Ge–Cr nanoclusters. Additionally, we detect an asymmetric, isotropic resonant line clearly distinguished in the whole temperature range, T=4–300 K, which corresponds to a paramagnetic resonance of the charge carriers in the Ge0.99Cr0.01 nanowires. On the base of our previous studies, we compare properties of the charge carriers in germanium nanowires doped with different transition metals. We demonstrate that the effective g-factor related to charge carriers is reduced with an increase in the spin-orbital interaction in the row: Mn2+, Cr2+, Fe3+, and Co2+.
