Abstract
We report the preparation and investigation of ferromagnetic La0.67Sr0.33MnO3 (LSMO) thin films with orthogonally (along (110) and (1ı̄0)) distributed nanometer-scale cracks. When the density of cracks reaches ∼104 cm−1, the magnetoresistance MR=(RH−R0)/R0>−30% was observed in the magnetic fields ≤200 Oe 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.
