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:
      American Physical Society March Meeting 2005 (contributed talk)
         Title: Ferromagnetic resonance studies of Co and Pt/Cu/Co/Cu/Pt layered ultra-thin films
      Condensed Matter Seminar at Colorado State University 2005 (invited talk)
         Title: Magnetization damping in ultra-thin Co films: evidence for spin pumping
       Magnetism and Magnetic Materials Conference 2005 (poster)
         Title: Ferromagnetic resonance study of polycrystalline Cobalt ultra-thin films

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.
