In the superconducting state, the in-plane electrical resistivity of the crystal is measured for fields up to 16 T and as a function of field direction, in order to understand how the vortex dynamics is affected by the presence of defects. A strong deviation from the slightly anisotropic crystal (electronic anisotropy constant 7 ~ 1.08) is observed as a steep angular dependence, which is interpreted as a signature of the presence of correlated defects. The influence of the correlated defects on the critical current is studied through the angular dependence of the magnetization, and compared to numerical simulations. 000044958 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T12$$9info:eu-repo/grantAgreement/ES/MICINN/ENE2011-29741$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2011-22719 000044958 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000044958 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000044958 700__ $$aCrivillero, V.A. 000044958 700__ $$aFranco, D.G. 000044958 700__ $$0(orcid)0000-0002-8753-2397$$aBadía-Majós, A.$$uUniversidad de Zaragoza 000044958 700__ $$aGuimpel, J. 000044958 700__ $$aNieva, G. 000044958 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDepartamento de Física de la Materia Condensada$$cFísica de la Materia Condensada 000044958 773__ $$g507 (2014), 012001 [4 pp]$$pJ.
