摘要: We reveal for the first time through a theoretical first-principles study that the adsorption of a nonmagnetic π-conjugated organic molecule on a ferromagnetic surface locally increases the strength of the magnetic exchange interaction between the magnetic atoms binding directly to the molecule. This magnetic hardening effect leads to the creation of a local molecular mediated magnetic unit with a stable magnetization direction and an enhanced barrier for the magnetization switching as compared to the clean surface. Remarkably, such a hybrid organic-ferromagnetic system exhibits also a spin-filter functionality with sharp spin-split molecularlike electronic features at the molecular site. 其他題名: Phys Rev Lett 出版者: United States: American Physical Society (APS) 出版日期: 2013-09-04 出處: Physical Review Letters, 2013-09, Vol.111 (10), p.106805, Article 106805 資源來源: APS online 識別號: ISSN: 0031-9007 識別號: ISSN: 1079-7114 識別號: EISSN: 1079-7114 識別號: DOI: 10.1103/physrevlett.111.106805 識別號: PMID: 25166694
