Molecular beam epitaxy growth and characterization of self-assembled MnAs wires on highly oriented pyrolytic graphite
(Color online) Noncontact AFM image of the MnAs/HOPG surface: (a) 11 min MnAs sample and (b) 3.5 min MnAs sample. The scan area is for both.
(Color online) (a) Noncontact AFM image of MnAs/HOPG (11 min MnAs) showing the MnAs wire dimensions. (b) STM image of the MnAs free area showing the carbon atoms of HOPG. The STM scan parameters were and . Image size is .
Magnetization measurement of MnAs/HOPG at 295 K.
