The resistivity of La[sub 0.82]Ca[sub 0.18]MnO[sub 3] single crystal has been investigated as a function of external magnetic field and separately under an applied current flow. The measurements were carried out at various temperatures below and above the ferromagnetic transition temperature T[sub C]. It has been found that the dynamic electroresistance exhibits stunning similarities to the colossal magnetoresistance at the corresponding temperatures. The correlation observed between the electric- and magnetic-field effects is attributed to electrically induced magnetoresistance. © 2001 American Institute of Physics.

    The ferromagnetic properties of epitaxial La0.5Sr0.5CoO3 thin films have been studied. The magnetic transition is affected by both strain and finite thickness. We have used a series of films of different thicknesses and on different substrates in order to quantitatively determine the change in...

    We investigate the spin-polarized transport of GaMnAs nanolayers in which a ferromagnetic order exists below a certain transition temperature. Our calculation for the self-averaged resistivity takes into account the existence of an impurity band determining the extended ('metallic' transport) or...

    We present an element-resolved study of the valence and magnetic properties of LaCoO3 thin films grown via pulsed laser deposition. The Co L edge x-ray absorption shows that ferromagnetic (FM) order arises from a slight hole doping of the system presumably due to nonstoichiometry, which in the...

    We report measurements of the anisotropic magnetoresistance (AMR) of epitaxial thin film and polycrystalline samples of La0.65Ca0.35MnO3. Near the metal-insulator transition (MIT) temperature the AMR of both polycrystalline and thin film samples exhibit a peak. However at temperatures well below...
