Abstract :
Detailed knowledge of magnetization reversal and possible magnetic configurations in magnetic nanostructures is essential for high-density magnetic memory. Magnetism of nanostructured magnets, of size comparable to or smaller than ferromagnetic domain size, offers a great potential for new physics. We present results of a systematic study of magnetic reversal in sub-100 nm nanodots, and how this reversal can be affected by various types of anisotropy, temperature, and exchange bias.
