Magnetic Anisotropy of a Single Cobalt Nanocluster
Magnetic Anisotropy of a Single Cobalt Nanocluster
Using a new micro-SQUID setup, we investigate magnetic anisotropy in a single 1000-atom cobalt cluster. This system opens new fields in the characterization and understanding of the origin of magnetic anisotropy in such nanoparticles. For this purpose, we report three-dimensional switching field measurements performed on a 3 nm cobalt cluster …
