This work focuses on the magnetic optimization of La2CoMnO6 (LCMO) double-perovskite ceramics by Ti-doping at Mn-site. LCMO ceramics with different Ti-doping contents (LCMTxO, x = 0.1–0.4) were prepared by plasma activated sintering, and the effect of Ti-doping on the structural and magnetic properties of the ceramics is studied systematically. All the ceramics exhibit dense structure and small grain size, with a monoclinic P21/n crystalline structure. With the increasing of Ti-doping content, the proportions of Co2+ and Mn4+ in the LCMTxO cer...
