These oscillations are associated with quantum interferences, tuned by Hx, between different spin tunneling paths linking two excited magnetic states. The oscillation period is determined by the quantum mixing between the ground S=10 and excited multiplets. These experiments enable us to quantify such mixing. We find that the weight of excited multiplets in the magnetic ground state of Fe8 amounts to approximately 11.6%. 000063231 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E98-MOLCHIP$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2012-38318-C03 000063231 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000063231 590__ $$a7.728$$b2013 000063231 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b6 / 78 = 0.077$$c2013$$dQ1$$eT1 000063231 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063231 700__ $$0(orcid)0000-0001-6284-0521$$aLuis, F.$$uUniversidad de Zaragoza 000063231 700__ $$aMontero, O. 000063231 700__ $$aBarbara, B. 000063231 700__ $$aBallou, R. 000063231 700__ $$aMaegawa, S. 000063231 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDepartamento de Física de la Materia Condensada$$cFísica de la Materia Condensada 000063231 773__ $$g111, 5 (2013), 057201 [5 pp]$$pPhys. rev. lett.$$tPHYSICAL REVIEW LETTERS$$x0031-9007 000063231 8564_ $$s731490$$uhttps://zaguan.unizar.es/record/63231/files/texto_completo.pdf$$yVersión publicada 000063231 8564_ $$s117377$$uhttps://zaguan.unizar.es/record/63231/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000063231 909CO $$ooai:zaguan.unizar.es:63231$$particulos$$pdriver 000063231 951__ $$a2017-11-16-11:05:32 000063231 980__ $$aARTICLE
