MUTSUHIRO SHIMA

Career Highlights

Professor Shima has clarified the origin of ferromagnetic moment detected in gamma-iron nanoparticles trapped in carbon nanotubes, identified the mechanism of interlayer coupling in giant magnetoresistance (GMR) multilayer structures that are governed by the RKKY-type indirect interactions and magnetostatic ‘orange-peel’ coupling between magnetic layers, and developed a magnetic phase diagram for nanoparticles that gives guidance in designing nano-sized magnetic particles by their shape, size and micro-structure. He’s participated in 15 journal paper reviews, 4 proposal reviews within the last two years; and was a conference session chair for the Materials by Design Symposium at the TMS Meeting in 2004 and the Intermag Conference in 2005.

Research Areas

Professor Shima's work impacts the fields of Nanotechnology, Microstructures, Microelectronics Technology, Metallurgy, Electronic Materials, and Particles. Dr. Shima's research interests are mainly focused on the nanostructure and properties relationship of novel magnetic and magnetoelectronic materials, including multilayered, patterned and self-assembled nano-scale structures, wires and particles for future applications such as data storage and sensor devices. Studies are carried out through materials processing including thin film depositions (sputtering, pulsed laser deposition, electrodeposition), structural modification (ion beam irradiation, annealing) and patterning (lithography, templates, self-assembling) combined with analysis of the structural, electrical, mechanical and magnetic properties.
