(a) of LCMO films as a function of their thickness. The line corresponds to a fit to . (b) Magnetization, normalized to the weight of the sample and to the thickness of the film, of several films.
Dependence of the coercive field of three samples in the thickness range with the square root of the temperature. Below about two regimes are observed. The dashed lines are the corresponding linear fits that indicate the blocking temperatures.
(Color online) (a) Resistance of three films (30, 15.5, and thick) with and without applied magnetic field. (b) MR defined as in the text for the three films evidencing the enhancement of the MR around and at low temperatures of the film.
(Color online) Schematic representation of the magnetic structure of the SP films at different temperatures and applied magnetic fields. The lowest part presents a zoom of the interface between two magnetic clusters.
(a) MR at of different thin films and a polycrystalline pellet. The gray line is the fit of the 6.5 nm film. (b) MR at 200 and of the film. The lines are the fits as explained in the text.
