Outline of Final Research Achievements

We found that the electron momentum distributions of 3d and 4f ferromagnets show that (i) asymmetry upon magnetic field reversal, (ii) the asymmetry is proportional to their magnetizations, (iii) the asymmetry vanishes above the Curie temperatures. Furthermore, we found that the differential spectrum of electron momentum distribution between majority and minority spin bands of Fe is well reproduced by the first principles band calculation. From the spin-polarized electron momentum distributions of full and half Heusler alloys (Co2MnSi(Al) and NiMnSb), we found higher half-metallicity of Co2MnSi and NiMnSb. Through spin-polarized positronium annihilation measurement, we found the appearance of surface spin polarizations on nonmagnetic Pd, Pt, Ta, W and Bi/Ag bilayer due to application of DC current. From spin polarized positron annihilation measurements for ZnO and SnO2, we found that cation vacancies have magnetic momemt.
