It is well known that Neel skyrmions of definite chirality are stabilized by the Dzyaloshinskii-Moriya exchange interaction (DMI) in bulk non-centrosymmetric materials or ultrathin films with strong spin-orbit coupling at the interface. In this work, we show that soft magnetic (permalloy) hemispherical nanodots are able to host three-dimensional chiral structures (half-hedgehog spin textures) with non-zero tropological charge. They are observed at room temperature, in absence of DMI interaction and they can be further stabilized by the magnetic field arising from the Magnetic Force Microscopy probe. Micromagnetic simulations corroborate the experimental data. Our work implies the existence of a new degree of freedom to create and manipulate complex 3D spin-textures in soft magnetic nanodots and opens up future possibilities to explore their magnetization dynamics. 000096205 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón$$9info:eu-repo/grantAgreement/ES/DGA-FSE/E13-20R$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2016-78591-C3-3-R$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2015-73775-JIN$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2016-76824-C3-1-R$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2017-83632-C3$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2018-102627-T$$9info:eu-repo/grantAgreement/ES/MINECO/MDM-2014-0377$$9info:eu-repo/grantAgreement/ES/MINECO/S2018-NMT-4321 000096205 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttp://creativecommons.org/licenses/by-nc/3.0/es/ 000096205 590__ $$a7.79$$b2020 000096205 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b62 / 333 = 0.186$$c2020$$dQ1$$eT1 000096205 591__ $$aPHYSICS, APPLIED$$b23 / 160 = 0.144$$c2020$$dQ1$$eT1 000096205 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b32 / 178 = 0.18$$c2020$$dQ1$$eT1 000096205 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b29 / 106 = 0.274$$c2020$$dQ2$$eT1 000096205 592__ $$a2.037$$b2020 000096205 593__ $$aNanoscience and Nanotechnology$$c2020$$dQ1 000096205 593__ $$aMaterials Science (miscellaneous)$$c2020$$dQ1 000096205 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000096205 700__ $$aJaafar, M. 000096205 700__ $$aFernandez-Roldan, J.A. 000096205 700__ $$aGoiriena-Goikoetxea, M. 000096205 700__ $$0(orcid)0000-0001-6771-6941$$aPablo-Navarro, J. 000096205 700__ $$aGarcia-Arribas, A. 000096205 700__ $$aGuslienko, K. 000096205 700__ $$0(orcid)0000-0002-6761-6171$$aMagen, C.$$uUniversidad de Zaragoza 000096205 700__ $$0(orcid)0000-0001-9566-0738$$aDe Teresa, J.M.$$uUniversidad de Zaragoza 000096205 700__ $$aChubykalo-Fesenko, O. 000096205 700__ $$aAsenjo, A. 000096205 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
