NRC Fellowship Awarded

I have been awarded the prestigious National Research Council Fellowship to pursue fundamental spin properties of 2D and low dimensional materials. Its my privilege to work with Dr. Mark Keller and Dr. Tom Silva in the Quantum Electromagnetic Division at the National Institute of Standards and Technology.

Symmetry breaking of magnetic vortices before annihilation (APL Cover)

In this work we created two unique energy landscapes by applying a magnetic force field parallel and anti-parallel to to the vortex polarity. This lead to the breakdown of the rotational symmetry of the vortex state into unique asymmetric identities.

Coherence and modality of driven interlayer-coupled magnetic vortices - Nature Communications

In this work we directly observed the effects of fundamental magnetic interactions between two driven magnetic vortices. See the press release below for a more general explanation. The figure on above is the magnetic signal of two vortex cores (radius ~10nm) reconstructed from an experimental Lorentz image of a multilayered nano-disc during a quasi-static magnetic field sweep.
