Reduction of critical field for magnetic and orbital-ordering phase transition in impurity-substituted Nd0.45Sr0.55MnO3 crystal

Reduction of critical field for magnetic and orbital-ordering phase transition in impurity-substituted Nd0.45Sr0.55MnO3 crystal

We have investigated the Mn-site substitution effect in Nd0.45Sr0.55MnO3 single crystal, which has an A-type layered antiferromagnetic (A-AFM) phase with the 3dx2−y2-type orbital-order. Substitution of Fe or Ga for Mn-site suppresses both the A-AFM order and competing ferromagnetic (FM) correlation,...
