Description

La0.7Sr0.3Mn1-xRuxO3, 0≤x≤0.2 samples were prepared both in bulk and thin film formed using pulsed laser deposition. Magnetization measurements of bulk samples indicate a marginal decrease in Tc from 366 to 335 K up to 15% Ru substitution in Mn site. X-ray diffraction of the left-angle 100 right-angle oriented epitaxial films indicate a monotonic increase in the lattice parameter with Ru doping. The magnetoresistive behavior of the Ru substituted films are comparable with the parent La0.7Sr0.3MnO3 films. Unlike other elemental substitution in Mn sites, the effect of Ru to stabilize magnetic ordering at elevated temperatures is exceptional. copyright 1998 American Institute of Physics
