Rezumat | |
A single crystal of gallium antimonide doped with 3 at.% 57Fe was obtained via the Czochralski method. The Mössbauer investigations revealed four iron patterns - one diamagnetic and three Fe magnetically ordered sites, even at room temperature. The data suggested that iron containing compounds are formed at grain boundaries and the microscopy images revealed the presence of two types of boundaries and holes of different shape and size. The EDX
spectrum provided different amounts of Fe in the crystal (GaSb) and, respectively, at the boundary area. |

Măsurătorile spectrelor Mössbauer la temperatura camerei demonstrează prezenţa a patru stari distincte a nucleelor de Fe. În cristalele GaSb dopat cu Fe se formeasă o fracţie cu proprietăţi magnetice bine pronunţate cu compoziţia FeGa3. Această fracţie se formează preponderent la frontiera dintre dislocaţii şi defecte a reţelei cristaline.</description> </descriptions> <formats> <format>application/pdf</format> </formats> </resource>
