Abstract :
Uniform thin films of polycrystalline α-iron were obtained by decomposing a stream of Fe(CO)5 in a flow reactor using 193-nm ArF excimer laser pulses. The films are optically flat and 2.6 μm thick, but they have a spiculate columnar microstructure with a mean column width of 0.2 μm. The films show perpendicular magnetic anisotropy. The Mossbauer spectra of the surface and bulk can be fitted by assuming an angle of 37° between the magnetization direction and the normal to the film
