The magnetic ordering of four Tb3+-doped manganites and cobaltites, La0.7Tb0.1Sr0.2MnO3, La0.7Tb0.1Ca0.2MnO3, La0.7Tb0.1Sr0.2CoO3 and La0.7Tb0.1Ca0.2CoO3, have been studied by means of neutron diffraction and SQUID magnetometry. All the samples were prepared by sintering of sol–gel precursors and their orthorhombic or rhombohedral perovskite structures at room and low temperatures were refined. A long-range ferromagnetic (FM) order was detected at the Mn and Co sites.
