We report the synthesis of single-crystal iron germanium nanowires via chemical vapor deposition without the assistance of any catalysts. The assembly of single-crystal FeGe2 nanowires with tetragonal C16 crystal structure shows anisotropic magnetic behavior which is ferromagnetically coupled perpendicular to the wires and antiferromagnetically coupled parallel to the wires’ long axis. Single FeGe2 nanowire devices were fabricated using e-beam lithography. Transport in these devices show two resistivity anomalies near 250 K and 200 K which are likely signatures of the two spin density wave states in FeGe2.
