Our results indicate that both processes are also possible in quasi-1D quantum wires in an in-plane B field, B-parallel to. Crossings of opposite-spin 1D subbands resemble magnetic phase transitions at zero dc source-drain bias, but display anticrossings at high dc bias. Our data also imply that the well-known 0.7 structure may evolve into a spin-hybridized state in finite dc bias. date: 2008-06-06 publisher: AMER PHYSICAL SOC official_url: http://dx.doi.org/10.1103/PhysRevLett.100.226804 vfaculties: VENG oa_status: green language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_batch elements_source: Web of Science elements_id: 319990 doi: 10.1103/PhysRevLett.100.226804 language_elements: EN lyricists_name: Pepper, Michael lyricists_id: MPEPP38 full_text_status: public publication: PHYS REV LETT volume: 100 number: 22 article_number: 226804 issn: 0031-9007 citation: Graham, AC; Simmons, MY; Ritchie, DA; Pepper, M; (2008) Anticrossing of spin-split subbands in quasi-one-dimensional wires.
