Course Description

This 3 unit course is intended to introduce graduate students to state-of-the-art nanofabrication techniques and physical properties of magnetic nanostructures. Particular emphasis will be put on those techniques available on campus. First, various types of nanofabrication techniques, their capabilities and limitations in achieving magnetic nanostructures, will be discussed. Specifically, I will cover physical and chemical deposition (vacuum basics, sputtering, evaporation, MBE, pulsed laser deposition, electrodeposition) and nanopatterning techniques (photo- and e-beam lithography, x-ray lithography, laser interference lithography, scanning probe lithography, step growth methods, nanoimprint, shadow masks, radiation damage, self-assembled structures, and the use of nanotemplates).  Then I will review the common methods for structural, chemical, and magnetic characterizations (x-ray and electron diffraction, electron microscopy, EDX, SQUID, VSM, AGM).  Physical properties of these nanostructures will be discussed, including properties of single nanodots, magnetic interactions in arrays, magnetic behavior of nanostructured wires, magneto-transport phenomena, and properties of hybrid systems. Some lab demonstrations and/or experiments will be included.
