摘要：

Co2FeGa Heusler alloy nanowires with diameters of about 30, 60 and 110 nm were prepared using a template-assisted electrochemical deposition method. We observe the different angular dependences of coercivity and remanence ratio for these samples. Magneto-transport measurements show that the 30 nm diameter Co2FeGa nanowires has a large magnetoresistance up to -56%, which is much higher than 60 and 110 nm diameter Co2FeGa nanowires. This is the first time that the magnetoresistance properties of Co2FeGa nanowires were presented.
