The recent development of the capability to produce thin GaMnN wires in the Peidong Yang group at Berkeley offers a unique opportunity to study the nature of semiconductor ferromagnetism in one dimensional systems, an issue which is currently topical as the transportation of information in a spintronics based technology will occur via wires that will approach the 1D limit. We will therefore embark on fundamental characterization of GaMnN wires from both a transport and magnetic point of view. For transport characterization, high resolution lithographic techniques will be used to fashion contacts onto a single wire and measure the magnetoresistance and transport anisotropy properties. In parallel, direct magnetic measurements will be performed by SQUID on array of wires to determine the correlations between magnetic and transport properties. Ultimately, the two approaches will be merged, as nano-patterned Hall bars will be used as probes to measure the magnetic properties of a single GaMnN wire.
