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 N$_2$ partial
gas flow $(R_{N_{2}})$ was varied in close intervals to
achieve the optimum conditions for the growth of the tetra
cobalt nitride (Co$_4$N) 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 Co$_4$N
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 Co$_4$N phase’s local
structure.},
