Abstract
The proximity effect of a C-type antiferromagnet with the spin canting at low temperature is investigated in the hybrid Nd0.35Sr0.65MnO3/YBa2Cu3O7 oxide system through magnetic and transport measurements. It is found that the onset of a spin-canted state destroys partially the superconducting order parameter. Interestingly, due to the instability of this spin-canted state, zero resistivity recovers at the offset of spin canting. Our result demonstrates clearly the high sensitivity of superconducting order parameter to a modulation of internal field.
