We have analyzed the magnetism of Ni features deposited on nonmagnetic substrates using a novel method: laser assisted chemical vapor deposition. Both coercivity and loop shape are determined on a scale of order 1 mm, which is much smaller than the lateral size of the features. The magnetization curves are fitted to a simple substructure morphology model, although there is secondary dependence of the coercivity on the shape of the structures.
