Bernhard, Christian 2019-08-01 We studied how the electronic, superconducting, and magnetic properties of YBa2Cu3O7/Nd1−x(Ca1−ySry )xMnO3 multilayers depend on the tolerance factor and the hole doping of the manganite. In particular, we investigated the granular superconducting state and the related magnetic-field-driven insulator-to- superconductor transition that was previously discovered in corresponding multilayers with Pr0.5La0.2Ca0.3MnO3 [B. P. P. Mallett et al., Phys. Rev. B 94, 180503(R) (2016)]. We found that this granular uperconducting state occurs only when the manganite layer is in a charge/orbital ordered and CE-type antiferromagnetic state (Mn-CO/OO). The coupling mechanism underlying this intriguing proximity effect seems to involve the domain boundaries of the Mn-CO/OO and/or the charge disordered regions of the manganite layer that become more numerous as the hole doping is reduced below x = 0.5. application/pdf https://folia.unifr.ch/global/documents/308043 https://folia.unifr.ch/documents/308043/files/ber_gsc.pdf https://folia.unifr.ch/documents/308043/files/ber_gsc_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevMaterials.3.084801 info:eu-repo/semantics/openAccess License undefined Physical Review Materials. - 2019, vol. 3, no. 8, p. 084801 info:eu-repo/classification/udc/53 Granular superconductivity and charge/orbital order in YBa 2 Cu 3 O 7 /manganite trilayers http://purl.org/coar/resource_type/c_6501
