題名: | A combined first principle calculations and experimental study on the spin-polarized band structure of Co-doped PbPdO2 | 作者: | 郭光宇 Guo, Guang-Yu |
貢獻者: | 應物所 | 日期: | Nov-2012 | 上傳時間: | 24-Jan-2014 | 摘要: | With x-ray spectroscopy and first-principles calculations, we expose the electronic structure, near the Fermi level, of Co-doped PbPdO2 composed of O 2p-Pd 4d hybridized states with an additional contribution of a spin-polarized Co 3d state at either a greater or smaller energy. The spin-polarized Co 3d states interacting with O 2p-Pd 4d hybridized states cause spin splitting at the band edge. Fascinating physical properties such as high-temperature ferromagnetism thus arise in Co-doped PbPdO2. Results will help in the design of materials with desired electronic structures and the control of spin polarization with chemical doping. | 關聯: | Applied Physics Letters, 101(22), 222104 | 資料類型: | article | DOI: | http://dx.doi.org/10.1063/1.4768293 |
