Dipolar interactions in arrays of ferromagnetic nanowires: a micromagnetic study

, 2010
We explore the behavior of periodic arrays of magnetic nanowires by micromagnetic simulations using the Nmag modeling package. A large number of modeling studies on such arrays of nanowires have been performed using finite size models. We show that these

Precessional switching of thin nanomagnets: analytical study

, 2003
We study analytically the precessional switching of the magnetization of a thin macrospin. We analyze its response when subjected to an external field along its in-plane hard axis. We derive the exact trajectories of the magnetization.
