Physical Review Letters, 87 (25), 256602-1-256602-4. https://doi.org/10.1103/PhysRevLett.87.256602.0031-90071079-7114https://hdl.handle.net/11441/150042We study spin-dependent magnetoconductance in mesoscopic rings subject to an inhomogeneous in-plane magnetic field. We show that the polarization direction of transmitted spin-polarized electrons can be controlled via an additional magnetic flux such that spin flips are induced at half a flux quantum. This quantum interference effect is independent of the strength of the nonuniform field applied. We give an analytical explanation for one-dimensional rings and numerical results for corresponding ballistic microstructures.application/pdf4 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Quantum transportNonuniform magnetic fieldsAharonov-Bohm ringinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1103/PhysRevLett.87.256602
