Sammanfattning

Different strategies for obtaining nanowires (NWs) with
ferromagnetic properties using the molecular beam epitaxy
(MBE) grown nanostructures combining GaAs and Mn were
investigated. Four types of structures have been studied:
(i) self-catalyzed GaAs:Mn NWs grown at low temperatures on
GaAs(100) substrates; (ii) GaAs:Mn NWs grown at high
temperatures on Si(100) substrates; (iii) GaAs–GaMnAs core–
shell NW structures; (iv) GaAs–MnAs core–shell NW
structures grown on Si(100). Structures of types (i), (iii), and
(iv) exhibit ferromagnetic properties.
