摘要

Magnetic properties of the double perovskite oxide, Sr_2TiMnO_6, have been studied by means of bulk magnetization and powder neutron diffraction experiments. Low field magnetization data reveal transitions at ~45 K (T_c) and at ~15 K (T_N). A magnetic moment value of only ~0.23 μB/F.U. is attained at 5 K in the 7 T field. Powder neutron diffraction studies suggest the possible antiferromagnetic order in this compound at 12 K with moments of ~0.5 μB at the Mn site.
