Magnetic nanoparticle composed nanowires fabricated by ultrashort laser ablation in air

Abstract

In this paper, a method for formation of nanoparticle composed wires of magnetic materials is presented. The method is based on ultrashort laser ablation in air at atmospheric pressure in the presence of external magnetic field. The material ablated at these conditions is composed of nanosized spherical particles that form chains with length of a few tens of microns. These structures are deposited on the substrate's surface as they are arranged parallel to the applied magnetic field. The obtained results can be used for designing a technology for magnetic materials assembly at open environment conditions.
