Modulation of superconductivity by spin canting in a hybrid antiferromagnet/superconductor oxide

Awadhesh Mani, T. Geetha Kumary, Daniel Hsu +2

The proximity effect of a C-type antiferromagnet (C-AFM) with the spin canting at low temperature is investigated in the hybrid Nd0.35Sr0.65MnO3(NSCO)/YBa2Cu3O7(YBCO) oxide system…
