abstract = {We studied the growth behavior, structural, electronic, and
magnetic properties of cobalt nitride (Co-N) thin films
deposited using direct current (dc) and high power impulse
magnetron sputtering (HiPIMS) processes. The N2 partial gas
flow () was varied in close intervals to achieve the optimum
conditions for the growth of the tetra cobalt nitride (Co4N)
phase. We found that Co-N films grown using the HiPIMS
process adopt (111) orientation as compared to the growth
taking place along the (100) direction in the dcMS process.
It was observed that HiPIMS grown Co-N films were superior
in terms of crystallite size and uniform surface morphology.
The local structure of films was investigated using x-ray
absorption fine structure (XAFS) measurements. We found that
the high energy of adatoms in the HiPIMS technique assisted
in the more excellent stabilization of fcc-Co and the novel
Co4N phase relative to the dcMS process. Magnetic properties
of Co-N thin films were studied using magneto-optical Kerr
effect, vibrating sample magnetometry and polarized neutron
reflectivity. It was found that though the saturation
magnetization remains almost similar in films grown by dcMS
or HiPIMS processes, they differ in terms of their magnetic
anisotropy. Such variation can be understood in terms of
differences in the growth mechanisms in dcMS and HiPIMS
processes affecting the resulting Co4N phase’s local
structure.},
