Structural evolution of MnTi0·8Ru0·2O3

Abstract

Here We present the structural studies on MnTi 1-x Ru x O 3 (x=0, 0.2) compounds. The role of Ti ions in the magnetism of MnTiO 3 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 MnTiO 3 . 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.Introduction:
