Evan Giacchino was awarded College Honors at CURC 2015 for his poster entitled “Experimental Effects of Dzyaloshinskii-Moriya Interaction on Magnetic Domains”. Evan has been working with Prof Kristen Buchanan’s group on the challenging task of preparing lithographically-patterned magnetic/non-magnetic bilayer nanostructures on special substrates that have a 0.5-mm wide window that is only 50 nm thick. The goal of his project is to look for subtle effects on the magnetic domain configurations caused by the interfacial Dzyaloshinskii-Moriya interaction, an antisymmetric exchange interaction that arises at the interface between a magnetic material and a non-magnetic material that has high spin-orbit coupling, using high-resolution Lorentz transmission electron microscopy (L-TEM) to obtain images of the magnetic domains. The imaging will be done at CSU’s new high-resolution TEM facility. Research on magnetic nanostructures is important for a variety of technologies including magnetic memory and logic devices, sensors, communications, and for biomedical applications.
