  Title Magnetoresistance effect in (La, Sr)MnO_3 bicrystalline films Type Journal Article
  Year 2010 Publication Journal of Physics: Condensed Matter Abbreviated Journal  
  Volume 22 Issue 34 Pages 346007  
  Keywords  
  Abstract The angular dependence of the magnetoresistance effect has been measured on bicrystalline La 0.75 Sr 0.25 MnO 3 films. The measurements have been performed on an electronically lithographed Wheatstone bridge. The study of the angular dependence of both the magnetoresistance and the resistance of single-crystalline and grain-boundary regions of the samples allowed us to isolate two contributions of low-field magnetoresistance in manganites. One of them is associated with the spin–orbit effect, i.e. the anisotropic magnetoresistance of ferromagnetic compounds, and the other one is related to spin-disorder regions at the grain boundary. Complementary x-ray diffraction, ferromagnetic resonance and low temperature magnetization experiments contribute to the characterization of the magnetic anisotropy of the samples and the general comprehension of the problem.

  Title On the evidence for electron-electron scattering in the electrical resistivity of In Type Journal Article
  Year 1970 Publication Solid State Communications Abbreviated Journal Solid State Commun.  
  Volume 8 Issue 24 Pages 2129-2133  
  Keywords  
  Abstract Experimental measurements of the electrical magnetoresistivity of high purity Indium at low temperatures have been performed and clearly indicate that:

1. (a) A generalized Kohler's rule can be used to describe all experiments.

2. (b) A reliable method is therefore obtained for extrapolating the zero magnetic field resistivity to temperatures below the superconducting transition temperature.

3. (c) Clear-cut and reliable data show that no T2 dependence of the resistance is found; therefore no evidence of electron-electron interaction appears, contrary to information previously reported in the literature.
