Crystals of Pb3Mn7O15 doped with titanium ions have been synthesized. The study of the structural properties showed that titanium ions occupy positions in the “columns” between the planes, which leads to a weakening of the exchange interaction between the planes. The temperature dependences of magnetization and heat capacity revealed two anomalies at 62 K and 35 K. At 62 K, a long-range magnetic order presumably appears, and at 35 K a spin-reorientation transition occurs, as in Pb3Mn7O15.
