Precessional switching in arrays of iron nano-magnets. — •Fabrizio Porrati and Michael Huth — Physikalisches Institut, J. W. Goethe-Universität, Max-von-Laue-Strasse 1, 60438 Frankfurt am Main

We present a bit addressing scheme for magnetic ram based on the application of two successive unipolar field pulses. We employ micromagnetic simulations to study the switching behaviour of an isolated nanomagnet as function of the pulses length. We discuss the role of the dipolar interaction by varying the relative distance of memory cells in an array of nanomagnets.
