Mn-Rich Nanostructures in Ge_1−𝑥Mn_𝑥: Fabrication, Microstructure, and Magnetic Properties

Figure 10

Cross-sectional TEM images of a sample with 𝑇_𝑆=70^∘C. (a) Bright-field TEM image. Mn₅Ge₃ precipitates are marked by arrows. (b) Dark-field TEM image recorded after selecting a characteristic reflex of the hexagonal Mn₅Ge₃ lattice. Bright regions indicate Mn₅Ge₃ precipitates. The dashed line is drawn to mark the interface between GeMn layer and Ge buffer layer. (c) High-resolution TEM of a typically coherent, hexagonal Mn₅Ge₃ precipitate, circled by the white line.
