Abstract
Proximity effects of superconductivity and antiferromagnetism are investigated in an Nd0.43Sr0.57MnO3/YBa 2Cu3O7 (NSMO/YBCO) heterostructure through the measurements of resistivity, magnetization, and magnetoresistivity. The evolution of superconducting transition temperature (Tc) and antiferromagnetic transition temperature (TN) with applied current density (J) and magnetic field (H) mark the profound influences of spin injection on destructing the superconductivity as well as the magnetic orders, which is reflected from the fact that both Tc and TN reduce significantly with increasing J. © 2009 American Institute of Physics.
