The work at UniFr has been supported by the Swiss National Foundation (SNF) through Grants No. 200020-153660 and No. CRSII2-154410/1.We show that in Pr_(0.5)La_(0.2)Ca_(0.3)MnO_(3)/YBa_(2)Cu_(3)O_(7) (PLCMO/YBCO) multilayers the low temperature state of YBCO is very resistive and resembles that of a granular superconductor or a frustrated Josephson-junction network. Notably, a coherent superconducting response can be restored with a large magnetic field which also suppresses the charge-orbital order in PLCMO. This coincidence suggests that the granular superconducting state of YBCO is induced by the charge-orbital order of PLCMO. The coupling mechanism and the nature of the induced inhomogeneous state in YBCO remain to be understood.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.94.180503open access537Insulator transitionPhase-transitionsInterfaceEllipsometryResistanceFilmsOrderElectricidadElectrónica (Física)2202.03 Electricidad
