Report: The summer research of Mr. Ryan Desautels (PhD student, Department of Physics and Astronomy, University of Manitoba, Winnipeg, Canada) at Prof. Ko-Wei Lin’s Lab, Department of Materials Science and Engineering, National Chung Hsing University, Taichung, Taiwan.
Mr. Ryan Desautels, a PhD student from Department of Physics and Astronomy, University of Manitoba, Winnipeg, Canada (supervised by Prof. Johan van Lierop), spent his time this summer 2012 working hard in my lab for the research project.
Firstly, Ryan fabricated nanocomposite Cu-Co magnetic thin films using a dual ion-beam sputtering deposition system, which he learnt to operate independently. Secondly, Ryan characterized the Cu-Co magnetic thin films that he made by using a series of analytical facilities located at the National Chung Hsing University and the National Yunlin University of Science and Technology. These analytical techniques include x-ray diffraction (for structures), transmission electron microscopy, TEM, (for microstructures), alternating gradient magnetometry (for magnetic properties), magnetoresistance (for magnetotransport properties), and x-ray photoelectron spectroscopy (for depth profile and bonding types). In addition, Ryan learnt how to prepare samples for planar-view and cross-sectional TEM. Further, Ryan gave an invited talk and tutorial in XMCD, XAS in my group meeting and showed my students how to analyze the grain sizes in TEM pictures by imaging process software. Experiments to determine the low temperature magnetic properties of these Cu-Co thin films will be carried out when he returns to Canada. The work that Ryan has completed on this project while a member of the SIT program will be submitted, in the near future, to international conferences and peer-reviewed publications.
I would like to thank the organizations in NSC of Taiwan and NSERC of Canada for holding the SIT (summer in Taiwan) program which has benefited the student from Canada and students in my group by getting together for experiments, measurements, discussion both in scientific results and/or culture differences between Canada and Taiwan.
