Abstract

The effect of manganese doping on the magnetic and structural properties of strontium titanate (SrTiO₃) was studied. Neutron powder diffraction, x-ray diffraction, magnetic measurements, scanning electron microscopy and energy dispersive spectroscopy of x-rays were utilized. Air-sintered Sr(Mn _xTi_1-x)O₃ (SMT) with x = 0:02 and x = 0:05 were homogeneous single phase orthorhombic (space group Pbnm) perovskite samples. The symmetry was orthorhombic already at room temperature, and no symmetry change was observed down to 11 K. An anomaly in the magnetic susceptibility was observed in x = 0:02 sample at 75 K. In contrast to earlier reports, no ferromagnetism was observed.
