Abstract
Disclosed herein are systems, methods, and apparatuses for manufacturing highly isotropic magnetic nanoparticles. In particular, manufacturing of spherical and amorphous particles suspended in a solvent by irradiating alloy targets submerged in a solvent using nanosecond-scale laser pulses is disclosed. The absence of shape and crystalline anisotropy in the particles yields a colloidal suspension with excellent soft magnetic properties which can be used to improve the performance of various medical diagnostic devices and consumer electronics.
