Microscopy and mossbauer studies of iron states in doped galium antimonide

Summary:

A single crystal of gallium antimonide doped with 3 at % 57 Fe 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 resence 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.
