Nominator's project description

Professor Maekawa is one of the leading solid-state physicists in Japan. His research interests span over a number of problems like magnetism, spin-electronics, system-correlated electrons, high-Tc supraconductors. Prof. Maekawa is especially renowned for his pioneering work in the field of the spin-polarized electronic transport - one of the highly controversial issues in solid-state physics today. Since 1988 Prof. Maekawa is Professor of physics and Chairman of the National Research Project ¿New Quantum Phenomena in Oxidic Transitional Metals".
