Laser synthesis and magnetic properties of monodispersed core-shell nanoparticles

This paper presents a method for fabricating size-selected nickel nanoparticles coated with oxide shells (shell thickness of about 2 nm). The size of the generated particles was controlled by a low-pressure differential mobility analyzer. The total mass of the deposited particles was estimated on th...

Description
Summary:This paper presents a method for fabricating size-selected nickel nanoparticles coated with oxide shells (shell thickness of about 2 nm). The size of the generated particles was controlled by a low-pressure differential mobility analyzer. The total mass of the deposited particles was estimated on the basis of their measured electric current. A high-resolution transmission electron microscope was used to observe the morphologies of the particles. We successfully synthesized a series of monodispersed (geometric standard deviation
