We report on the transport properties of La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (200 nm)/YBa{sub 2}Cu3O{sub 7-δ} (50 nm) (LSMO/YBCO) heterostructure in the presence and absence of magnetic field, deposited on LaAlO3 (001) substrate using pulsed laser deposition technique. X- ray diffraction pattern confirms that the grown heterostructure is single phase in nature. The temperature dependent resistivity shows a metallic behavior below 304 K, superconductivity is completely suppressed by the presence of thick LSMO layer. From resistivity-temperature (ρ-T) curve, we have also observed the metal to insulator transition temperature at 304 K and increases to higher temperature side (353 K) on the application of magnetic field. We found a maximum magnetoresistance ratio ∼47% at 246 K temperature. Temperature co-efficient of resistance is ∼1.7 % K{sup −1} at 202 K, can be useful for bolometric performances and temperature sensors.
