详细研究了锰掺杂量为x=0.1,0.3,0.5的LaTiO3样品中轨道重构对磁性质的影响.氧含量过掺杂的母体LaTi03未出现任何转变,但在锰掺杂的样品中80K附近出现明显的磁性质转变行为.锰掺杂量z一0.1的样品在温度小于45K低场情况下,伴有磁化强度的涨落,表明了在材料中电子相分离的出现.随着锰掺杂量的增加,通过对Ti3+离子t2g。轨道的有序的影响进而增强了体系的反铁磁成分.
Effect of orbital reconstruction on the magnetic properties of Mn-doped LaTiO3:(x=0. 1, 0. 3, 0. 5) is investigated in detail. These samples show a magnetic transition at around T = 80 K which is not present in the parent LaTiO3. Sample with x = 0. 1, show fluctuations in magnetization at low fields below T= 45 K indicating e- lectronic phase separation in the material. Increasing Mn content in the sample strengthens the antiferromagnetic phase by influencing the orbital ordering of hg orbitals in Ti3+ ion.
