摘要：

In this paper we report on the structural and magnetic properties of GeMn layers grown on Ge(001). We show that for the optimized Mn concentration (6%) and for optimized growth temperature (close to 130 degrees C, GeMn samples exhibit a high Curie temperature (higher than 400 K) and Anomalous Hall Effect up to room temperature. Our GeMn layers grown at low temperature (70 degrees C to 130 degrees C) are composed of vertical Mn-rich nano-colums. Samples grown at temperatures higher than 130 degrees C contain GeMn nanoclusters.
