Electrical Transport and Magnetic Properties of La$\text{}_{2}\text{}_{/}\text{}_{3}$ Pb$\text{}_{1}\text{}_{/}\text{}_{3}$ MnO$\text{}_{3}$ Thin Films

The magnetic and transport properties of epitaxial La$\text{}_{2}\text{}_{/}\text{}_{3}$ Pb$\text{}_{1}\text{}_{/}\text{}_{3}$ CuO$\text{}_{3}$ thin films deposited on SrLaGaO$\text{}_{4}$ substrate using dc magnetron sputtering technique are reported. The giant magnetoresistance effect (of about 50% at magnetic field of 1 T) was observed near the Curie temperature. Several mechanisms responsible for temperature dependence of resistivity are discussed. The effect of annealing was studied. It shifted the Curie temperature to the lower value, probably, because of the loss of oxygen.
