文摘
- •
Pure and Gd–Ti co-substituted samples were prepared by a facile sol–gel method.
- •
Structural phase transition from R3c to Pbnm and then to
was confirmed through Rietveld analysis.- •
Enhancement in net magnetization due to the cancellation of spiral spin cycloid.
- •
An anomaly at the vicinity of Neel temperature (TN) was observed for all the samples.
- •
Leakage current density has been reduced to 3–4 orders for the co-substituted samples.
