Abstract

We investigate the magnetic properties of arrays composed of Pd/Co/Pd nanodisks with diameters of 450, 650, and 850 nm, respectively, and having crowns fabricated by means of electron-beam lithography. The experimental results show that vortex nucleation and the annihilation of critical fields decrease as nano- structure diameter increases. A feature of the investigated nanostructures is a vortex state with magnetization higher than for flat nanodisks. This is in good agreement with micromagnetic simulations of disk + ring nano- systems.
