- An advanced deposition technique known as glancing angle deposition was used to fabricate randomly seeded magnetic cobalt columnar nanostructures. The existence of nanocolumns was confirmed by the cross-section scanning electron microscopy. The evolution in the magnetization reversal mechanism as a function of the film thickness was investigated. The coercivity $H_{C}$ and $M_{R}//M_{S}$ ratio (where $M_{R}$ and $M_{S}$ denote the remanent and saturation magnetization, respectively), derived from the magnetic hysteresis loops, are discussed as a function of the angle between the external magnetic field and the surface normal. The direction of the magnetization easy/hard axis and the columns inclination angle were determined on the basis of the angular dependences of the $H_{C}$ and the $M_{R}//M_{S}$. A crossover from the coherent rotation, based on the Stoner-Wohlfarth model, to the curling reversal mode was observed.
