Structural evolution of MnTi0.8Ru0.2O3

Here We present the structural studies on MnTi1-xRuxO3(x=0, 0.2) compounds. The role of Ti ions in the magnetism of MnTiO3 was unclear so here this issue has been tried to address in this manuscript. The magnetic susceptibility data shows that the 3-dimensional magnetic character has been improved in the doped MnTiO3. The x=0 compound goes paramagnetic to antiferromagnetic phase at a temperature 64K followed by a broad peak at a temperature 100K . But in x=0.2 compound the antiferromagnetic transition temperature has been shifted towards the lower temperature to 47.5K with a broad peak at temperature 79K. On the doping of Ru at Ti site a sharp anomaly is observed 47.5K in the case of x=0.2 compound. This sharp anomaly attributes to the improved 3D character of magnetism in this compound which is weak in x=0 compound.
