Abstract :
Nickel cylinders were grown by electroplating into Al2O 3 membranes. They have various lengths and radius around 20 μm and 0.15 μm respectively, they are highly crystalline and of constant radius throughout their length. Magnetic Force Microscopy indicates that they are single domain and that the reversal mechanism for the magnetization is indicative of curling for all angles between the anisotropy axis and the field direction, but independent of radius
