Dr. Chumak is currently a postdoctoral fellow at Technische Universität Kaiserslautern, Germany. He is an established expert in the area of linear and nonlinear spin wave dynamics. Recently, his research has focused on spin-wave dynamics in magnonic crystals: periodic magnetic structures with artificial magnonic band-gaps.

We are presently investigating the possibility of parametrically pumping spin waves with acoustic energy, in collaboration with Dr. Chumak. Such a parametric amplifier, could, in the future, be used to amplify signals on a spin wave bus interconnecting spintronic logic gates. His visit to Corvallis included discussions on on-going related experiments in our laboratory and an invited talk in the Department of Physics.

Dr. Imamura's visit to Corvallis prompted a collaboration on implementing Kerr microscopy for imaging domains in magnetic thin films.

Dr. Imamura-san is presently a Professor in the Department of Electrical Engineering at the Fukuoka Institute of Technology in Japan. His research includes magneto-optical characterization of II-VI magnetic semiconductors with a direct and wide optical band gap.

During his second visit, Dr. Imamura guided the completion of the Kerr microscopy setup. Magnetic domains were successfully imaged in Fe72.5Si12.5B15 wires prepared by Imamura-san.

Dr. Kwang-Ho Shin

Dr. Shin is presently a Professor in the Department of Information & Communication Engineering in Kyugsung University, Busan, Korea. His research focuses on magnetic sensors, precision measurement and design of sensor systems. We are currently collaborating on the design of a custom susceptometer for characterizing magnetic nano particles.
