Principal Investigator: Prof. A. Kent
I am conducting Ferro-Magnetic Resonance (FMR) studies of films made of
transition metal ultra-thin layers (few nanometers thick). The goal is to
study the magnetic properties and the magnetization relaxation mechanism of
films with a layered structure similar to spin transfer devices. Those
systems have potential applications as ultra-fast and high density magnetic
recording media.
Project funded by the National Science Foundation and the Office Of Naval
Research
• Scientific achievement:
- FMR measurements on ultra-thin layered magnetic films using coplanar
waveguides (CPW).
- Evidence for non-local damping effect in polycrystalline ultrathin Cobalt
films.
- Estimate of the effective spin mixing conductance of Pt|Cu|Co interfaces
for sputtered and
evaporated films.
• Academic responsibilities:
Supervision and training of NYU undergraduate and graduate students for
the charaterization of planar
microwave resonators, for performing FMR
measurements, and for thin films patterning using the
photolithography technique.
• Selection of presentations:

Advisor: Professor Mike Adams
Theoretical project on Vertical Cavity Surface Emitting Lasers within
Professor Adams' group.
VCSEL's are semiconductor microlaser diodes that emit light in a cylindrical
beam vertically from the surface of a fabricated wafer, and offers
significant advantages in comparison with the edge-emitting lasers currently
used in the majority of fiber optic communications devices.
I was part of the research team that was developing a FORTRAN program to
model the propagation of beams of light in VCSELs cavities. My work
consisted in studying at the influence of structural changes of the cavity
on the spontaneous emission. The results of this investigation led to the
derivation of a theoretical understanding of the structural dependence of
the spontaneous emission in VCSELs.
