Ferrofluids: Colloidal suspension of magnetic nanoparticles
Iron oxide nanoparticles are coated with surfactant and dispersed in a nonpolar liquid, forming a stable suspension. The leftmost image shows the spikes due to the alignment of the magnetic moments of nanoparticles with the magnetic field. The other image shows a bar magnet that pulls on the ferrofluid inside the vial.

IEEE 1st Annual Magnetics Society Summer School
I was awarded a travel grant to attend the first IEEE Magnetics Society Summer School on August 3-5, 2008. It was held at the University of Colorado at Colorado Springs. The lectures covered review of the fundamentals of magnetism, nanomagnetism, theory and modeling, magnetotransport, magnetic recording, future recording concepts, spin dynamics, ultrafast switching, and advanced characterization.
APS March Meeting 2008 in New Orleans, Louisiana
On March 10 - 14, 2008, the Functional Materials Lab of USF attended the annual APS March meeting. It was held at the Morial Convention Center. In this meeting I was able to present how powerful a tool the transverse susceptibility technique is for determining interparticle interaction strength in nanoparticles. The results of this study have recently been published in the Journal of Applied Physics.
