Abstract

We report the preparation and investigation of ferromagnetic La 0.67Sr0.33MnO3 (LSMO) thin films with orthogonally (along (110) and (1ī0)) distributed nanometer-scale cracks. When the density of cracks reaches ∼ 104cm-1, the magnetoresistance MR=(RH-R0)/R0 >-30% was observed in the magnetic fields ≤200Oe and temperature range from 5 to >300 K. The discussion about such unique feature will be done based on the spin-polarized electron tunneling and spin scattering. © 2004 Elsevier Ltd. All rights reserved.
