Anisotropic magnetoresistive properties of La1-xCaxMnO3 (x approximate to 1/3) film at temperatures far below the Curie temperature Academic Article uri icon

abstract

  • A sharp distinction between magnetoresistance (MR) behavior for the magnetic fields applied perpendicular (H) and parallel (H) to the film plane is found in colossal-magnetoresistance film La1-xCaxMnO3 (x 1/3). At increasing of H the MR is first negative (at H 4 kOe), then positive (4 kOe H 12 kOe), and then negative again (H > 12 kOe). At increasing of H the MR is positive below H 6 kOe and negative above it. In both cases the magnetic field was perpendicular to the current. The anisotropic behavior of this kind occurs only at low temperatures (T 18 K) and is quite different from the results of previous studies. 2000 Elsevier Science B.V. All rights reserved.
