When an external potential is applied, the time reversal symmetry is broken and the wave vector k of the circulating electrons that contribute to the current is spin-dependent. As the wave function phase depends upon the vector k, the closed path in the circuit produces spin-dependent current interference. This creates a physical scenario in which a spin-polarized current emerges, even in the absence of external magnetic fields or magnetic materials. It is possible to find points in the system\u2019s parameter space and, depending upon its geometry, the value of the Fermi energy and the spin\u2013orbit intensities, for which the electronic states participating in the current have only one spin, creating a high and totally spin-polarized conductance. For a potential of a few tens of meV, it is possible to obtain a spin-polarized current of the order of \u03bcA. The properties of the obtained electronic current qualify the proposed device as a potentially important tool for spintronics applications.<\/jats:p>","DOI":"10.3390\/nano12224082","type":"journal-article","created":{"date-parts":[[2022,11,21]],"date-time":"2022-11-21T04:13:36Z","timestamp":1669004016000},"page":"4082","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Totally Spin-Polarized Currents in an Interferometer with Spin\u2013Orbit Coupling and the Absence of Magnetic Field Effects"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3046-5365","authenticated-orcid":false,"given":"Victor","family":"Lopes","sequence":"first","affiliation":[{"name":"Departamento de F\u00edsica Aplicada, Universidad de Alicante, San Vicente del Raspeig, 03690 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8077-1873","authenticated-orcid":false,"given":"Guillermo","family":"Chiappe","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica Aplicada, Universidad de Alicante, San Vicente del Raspeig, 03690 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1442-108X","authenticated-orcid":false,"given":"Laercio C.","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Centro Federal de Educa\u00e7\u00e3o Tecnol\u00f3gica Celso Suckow da Fonseca CEFET\/RJ, Campus Nova Igua\u00e7u, Nova Igua\u00e7u, Rio de Janeiro 26041-271, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4147-722X","authenticated-orcid":false,"given":"Enrique V.","family":"Anda","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Pontif\u00edcia Universidade Cat\u00f3lica do Rio de Janeiro (PUC-Rio), Rio de Janeiro 22451-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1488","DOI":"10.1126\/science.1065389","article-title":"Spintronics: A Spin-Based Electronics Vision for the Future","volume":"294","author":"Wolf","year":"2001","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"323","DOI":"10.1103\/RevModPhys.76.323","article-title":"Spintronics: Fundamentals and applications","volume":"76","author":"Fabian","year":"2004","journal-title":"Rev.
