Kinetic effects in manganites

Measurements have been made on the resistivity $\rho$, thermo-EMF coefficient $\alpha$, magnetization $\sigma$, magnetoresistance ($\Delta \rho/\rho$ effect), and even thermomagnetic effect $\Delta \alpha$ for an $La_{0,6}Pb_{0,4}Ni_{0,18}Mn_{0,82}O_3$ single crystal in magnetic fields up to 14 kOe at temperatures from 80 to 600 K. There are marked anomalies in these physical parameters in the region of the Curie point.
