Abstract
Magnetic hysteresis loops have been measured for a 100 nm period array of 3 5 nm diameter nickel pyramids formed by interferometric lithography. Result s are compared with a computational model which describes a square array of Stoner-Wohlfarth particles. This allows the distribution of particle aniso tropies and easy axis directions, and the switching mechanism, to be inferr ed.
