Exploring the composition, phase separation and structure of AgFe alloys for magneto-optical applications
Researchers from the University of Tennessee and Oak Ridge National Lab used the Waviks' Vesta in situ to fabricate AgFe nanoparticles . Their work was published in Materials Science and Engineering: B. They then used these bimetallic alloyed particles to study the optical and magnetic properties of varying AgFe compositions.
(a) HAADF STEM image of an Ag-Ni nanoparticle, and associated EELS spectrum images for the (b) Fe bulk surface plasmon peak, (c) the Ag dipole peak, and (d) the Ag bulk surface plasmon peak. For a-c, the scale bar (shown in the bottom right corner of b) is 40 nm.
The teams from Oak Ridge National Lab and the University of Tennessee demonstrated multiple fabrication methods for AgFe nanoparticles. The magnetic and optical properties of AgFe phase separated nanoparticles have applications in several magnetooptical applications including magnetic resonance imaging and cancer therapy.
