A Closer Look at Magnetic Anisotropy reports on results related to the impact of magnetic anisotropy on the properties of a new type of nanocomposite consisting of ferromagnetic nanoparticles embedded in carbon nanotubes. The authors demonstrate that when each nanotube contains only one ferromagnetic nanoparticle, the magneto-elastic anisotropy leads to the formation of densely packed arrays of magnetically isolated nanoparticles. Following this, the aspects of perpendicular magnetic anisotropy of FeCoZr-CaF2 nanocomposite films induced by shape anisotropy of metallic nanoparticles are...
