  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 the one 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.
