Abstract :
We study the switching behavior of variously shaped, near-single-domain nanomagnets for nanomagnet logic (NML) applications. Magnets in the size range of 60 × 100 to 60 × 200 nm, with different lengths and end-shapes are fabricated and characterized, and the results compared to temperature-dependent micromagnetic simulations. In this study, the length of the nanomagnets is more important to the switching properties than is end shape. However, for sharper magnets, temperature fluctuations play a large role in determining the switching field.
