Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

The recent discoveries of 2D van der Waals (vdW) materials have led to the realization of 2D magnetic crystals. Previously debated and thought impossible, transition metal halides (TMH) have given rise to layer dependent magnetism. Using these TMH as a basis, an alloy composing of Fe1-xNixCl2 (where 0 ≤ x ≤ 1) was grown using chemical vapor transport. The intrigue for this alloy composition stems from the interest in spin canting and magnet moment behavior since NiCl2 has in-plane ferromagnetism whereas FeCl2 has out-of-plane ferromagnetism. While in its infancy, this project lays out a foundation to fully develop and characterize this TMH via cationic alloying. To study the magnetic properties of this alloy system, Vibrating Sample Magnetometry was employed extensively to measure the magnetism as a function of temperature as well as applied magnetic field. Future work with use a combination of X-Ray Diffraction, Raman, Scanning Electron Microscopy, and Energy-Dispersive X-Ray Spectroscopy Mapping to verify homogeneous alloying rather than phase separation. Additionally, ellipsometry will be used with Kramer-Kronig relations to extract the dielectric constant from Fe1-xNixCl2. This work lays the foundation for future, fruitful work to prepare this vdW cationic alloy for eventual device applications.
