Abstract
Abstract Nanostructure (La2/3Sr1/3)MnO3 thin films were epitaxial grown on SrTiO3 (0 0 1) single crystal substrate by pulsed laser deposition. Both high Curie temperature (Tc = 360 K) and high magnetoresistance (MR = −38% at 500 Oe magnetic fields and 320 K) were simultaneously achieved. The high Curie temperature was attributed to the high quality epitaxial LSMO films. The high low field magnetoresistance (LFMR) was attributed to the regular square nanostructure of the deposited LSMO films, where the boundaries serve as the barrier for spin-polarized tunneling and/or spin-dependent scattering. The high Tc and large MR made the LSMO film very useful in room temperature magnetic devices.
