N1  - This work has been supported by the EC Network SemiSpinNet (PITN-GA-2008-215368) and by the FunDMS Advanced Grant of the ERC. The authors thank M. Sawicki and O. Proselkov from IP PASc, Warsaw, Poland for SQUID measurements of GaAs-GaMnAs core-shell NWs.
AB  - 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.Right: Scanning electron microscopy image of Mn doped GaAs NWs with Ga droplets at the tops, grown by MBE on oxidized Si(100) substrate in the autocatalytic growth mode.
