Hi and welcome to my research homepage! I am the project leader of Magnetic nanostructures for post-CMOS electronics in the Functional Nanostructured Materials Group, within the Materials Science and Engineering Division in MML. This project is part of a broader IMS project, funded in 2008, that includes three other NIST laboratories: CNST, EEEL, and ITL.



As the name of my project suggests, we work with magnetic nanostructures that have potential post-CMOS applications.  MRAM and magnetic hard disk drives, for example, are technologies on the market today that our research directly impacts. Our research focuses on the fundamental physical and material causes of non-uniform magnetic behaviors in magnetic nanostructure assemblies.  Our goal is to overcome these non-uniformities so that magnetic-base devices can continue to grow as Moore’s law.



As a part of our funding, we have a FEI Titan, field-emission transmission electron microscope with field-free Lorentz and holography capabilities. In conjunction with the existing state-of-the-art nanofab tools at the Advanced Measurement Lab, and latest developments in the micromagnetic modeling code, OOMMF, we can finally get to the bottom of the root causes of non-uniformity in magnetic nanostructures.
