Abstract
Magnetic hysteresis loops have been measured for a 100 nm period array of 35 nm diameter nickel pyramids formed by interferometric lithography. Results are compared with a computational model which describes a square array of Stoner-Wohlfarth particles. This allows the distribution of particle anisotropies and easy axis directions, and the switching mechanism, to be inferred
