文摘

Aristate spherical nickel nanoparticles were synthesized via the ultrasound reduction method. Aristate spherical morphology of nickel nanoparticles maybe ascribe to PVP surfactant effect. Critical grain size of nickel is 42 nm, which is consistent to its theory value of ferromagnetic exchange length.
