Outline of Final Research Achievements |
We studied on the spin Seebeck effects for garnet ferrite films and the anomalous Nernst effects for magnetic semiconductor films for the purpose of clarifying the energy conversion mechanism using spin currents and developing the new energy conversion devices. The measurement equipment for both effects at low temperatures was developed to carry out our study. The garnet ferrite films were deposited by the metal organic decomposition (MOD) method, and the relation between their compositions and spin Seebeck effects was made clear. For the magnetic semiconductor films prepared by the molecular beam epitaxy (MBE) method, the anomalous Nernst effects was observed, and was investigated based on the Mott relation and the Boltzmann equation.
