Giant magnetoresistance in La₀.₇Pb₀.₃MnO₃ thin film
Epitaxial thin films of La₀.₇Pb₀.₃MnO₃ have been grown on (100) LaAlO₃ and (110) SrTiO₃ substrates by dc magnetron sputtering. The magnetic-field and temperature-dependent resistivity of as-deposited and post-annealed films was examined. At H=10kOe the maximum observed magnetoresistance ratio (R0-RH...
