Magnetic Properties of a Ni Nanonet Grown in Superfluid Helium under Laser Irradiation by Oksana Koplak, Elizaveta Dvoretskaya, Maxim Stepanov, Alexander Karabulin, Vladimir Matyushenko, Roman Morgunov

“…A nanonet consisting of ultrathin Ni nanowires (diameter <4 nm) and Ni nanoballs (diameter <20 nm) has been grown through laser ablation of a Ni target in superfluid helium. At a low Ni concentration, the nanonet consists mainly of nanowires and manifests a rectangular magnetic hysteresis loop, while an increase in the Ni concentration results in an increase in both the concentration and diameter of the nanoballs. …”
