The Ca₃CoMn_1-xTi_xO₆(x = 0, 0.05) samples were synthesized by a modified sol-gel method, and the microstructure, microtopography, and magnetic properties were investigated in detail. With substituting of Mn⁴⁺ ions by Ti⁴⁺ ions, the crystallinity and particle size of Ca₃CoMn_1-xTi_xO₆ (x = 0, 0.05) samples decrease. The Ti⁴⁺ doping also causes the high-temperature spin freezing phenomenon disappears, and the transition field of ↑↑↓↓ magnetic structure to ↑↑↑↓ magnetic structure increases obviously together with the faster dynamic behavior. These results suggest that the dilution effect of Ti⁴⁺ doping to Co-Mn-Co-Mn spin chains could reduce the degree of magnetic frustration and suppress the formation of short range magnetic order, for which will be beneficial for the establishment of more robust long range antiferromagnetic structure. The present research could serve as a reference on tuning the magnetic order and improving the multiferroic property of Ca₃CoMnO₆.

 通过改进的溶胶-凝胶法合成了Ca ₃ CoMn _{1- x} Ti _x O ₆（x = 0，0.05 ）样品，并详细研究了其微观结构，微观形貌和磁性。通过用Ti ⁴⁺离子代替Mn ⁴⁺离子，Ca ₃ CoMn _{1- x} Ti _x O ₆（x  = 0，0.05 ）样品的结晶度和粒径降低。钛⁴⁺掺杂还会导致高温自旋冻结现象消失，并且↑↑↓↓磁性结构向↑↑↑↓磁性结构的过渡场明显增加，并且动力学行为更快。这些结果表明，Ti ⁴⁺掺杂对Co-Mn-Co-Mn自旋链的稀释作用可以降低磁阻程度，并抑制短程磁阶的形成，有利于建立更坚固的磁链。远距离反铁磁结构。本研究可为调节Ca ₃ CoMnO ₆的磁性能级和改善多铁性提供参考。
