摘要：

Iron germanium nanowires and films were prepared via a high pressure catalyst free chemical vapor deposition on Ge(111) wafer. Both nanowires and films were identified to be FeGe2. However, nanowires exhibited a saturation in field dependent magnetization while that of film did not. Magnetic field dependent resistivity showed two drops in warming curve from 10-300K with a magnetic field of 6T and 9T. These abnormal drops might attribute to a less scattering of electrons from complex spiral structures. Temperature dependent alignment of spin in the longitudinal spiral and transverse spiral magnetic structure led to a variation of scattering probability with moving electrons. (C) 2018 Author(s).
