Magneto-transport properties of Si-based Nanowires

We report the growth and magneto-transport properties of Si-based, Mn$_{5}$SiC nanowires grown using chemical vapor deposition. High resolution transmission electron microscopy and x-ray diffraction studies show that the nanowires crystallize in Mn$_{5}$SiC orthorhombic structure. Ferromagnetic Mn$_{5}$SiC nanowires were grown using a coordination complex-based precursor. In the presence of an external magnetic field, Mn$_{5}$SiC nanowire-based devices exhibit spin dependent transport properties at room temperature. A large change in current with almost two orders of magnitude increase is observed when a small field is applied parallel to the axial direction of the nanowire. We will discuss in details the magneto-transport properties of Mn$_{5}$SiC nanowire based devices.
